Nirt: Nanophotonics For Optical Delay Engineering (Node) @ University of California-San Diego
A multidisciplinary team from the University of California, San Diego (UCSD), specializing in the fields of nanophotonics, nanooptics, optoelectronics, and material science and material processing are collaborating in developing Integrated Nanoscale Materials, Devices and Systems with special focus on Nanophotonics for Optical Delay Engineering (NODE). The aim of the project is to demonstrate chip-scale realization of multistage optical delay architectures using nanoscale photonic materials and devices in a waveguide configuration, taking advantage of the polarization degree of freedom. The largest thrust will be on investigation of resonant phenomena in nanophotonic optical components placed in proximity to each other and demonstration of their integration into Nanoscale Devices-and-System Architectures realizing programmable optical delays which are crucial for numerous applications including optical buffering for large optical data routing systems, true time delay phased arrays, and general digital optical signal processing architectures. Research efforts in methodology, design, fabrication and characterization of nanophotonic materials, devices and systems will be useful for students and researchers in the fields of nanophotonics, advancing the fundamental understanding of the near field resonant and nonresonant interactions between nanoscale devices, and enabling their effective integration with novel functionalities. We will also establish innovative education and outreach projects with the UCSD's Preuss School, designed for students in 6-12 grade coming from disadvantaged households.

Career: Chip-Scale Low-Power Nonlinear Optics Using Coupled Resonators and Crows @ University of California-San Diego
0642603
Intellectual merit: The goal of this project is to investigate and apply a recently-developed optical waveguiding technology based on coupled resonators and coupled-resonator optical waveguides for low-power tunable nonlinear optics. Chi-(3) based parametric processes and nonlinearly-assisted slow wave propagation will be developed for applications such as all-optical wavelength conversion, optical buffering and tunable time delay. The benefit is to avoid using expensive high-power solid-state lasers, difficult and environmentally-sensitive phase-matching layouts using bulk optics, and long lengths of optical fiber. Instead the devices efficiently use low optical power levels compatible with on-chip sources, modulators, and novel waveguide components which can engineer the dispersion and phase-matching conditions.
Optical sensing, metrology and data/image processing devices will benefit substantially from low-power on-chip programmable linear/nonlinear filtering functionality. Chip-scale nonlinear photonics will enable advanced optical networking functionality to be performed by end-user devices rather than only at the network core. Desktop computers, handheld notebooks and PDAs, and eventually cellular phones may have optical chipsets based on low-power, highly-efficient wavelength conversion and optical memory technology which will enable them to connect directly to the fiber-optic internet. Heterogeneous networks can be made more efficient, versatile, secure, cost-effective and adaptable if optical buffering and wavelength conversion can be de-centralized from the core routers and gateways without paying a high penalty in complexity or power consumption.
Broader impact: The PI has played a principal role developing several of the theoretical and experimental aspects of coupled-resonators (as an area of the rapidly developing field of micro-resonators) over the last five years. This CAREER proposal is fundamental to the PI's efforts on both the research and educational aspects of this field. The work will enhance the infrastructure for optical waveguide research at UCSD by creating a new facility for rapid measurement of dispersive and nonlinear optical properties of resonator-based devices. Instructional material for a novel graduate course "Optical Resonators and their Applications" will be prepared. Graduate and undergraduate student research will be supported, the participation of women in engineering will continue to be developed, and an outreach program for minority students will be enhanced with the involvement of the California Alliance for Minority Participation and the Preuss School at UCSD.

Mri: Development of a Frequency-Comb Nearfield Infrared Spectrometer @ University of California-San Diego
ECCS-0723055 S. Mookherjea, University of California, San Diego
Intellectual merit The goal of the proposed program is to advance IR near-field spectro-microscopy for experiments at the nanoscale through the development of a Scattering Scanning Nearfield Infrared Microscope (S-SNIM). Since many fundamental properties of matter have characteristic energy scales falling in the near and mid-infrared "fingerprint" energy range, infrared spectro-microscopy is one of the most widespread analytical techniques and is routinely employed in such diverse areas as national security, forensics, most of the natural sciences, art history, materials science and engineering. Therefore, an instrument that permits accurate mid-IR spectroscopic and microscopic measurements at the nanoscale will offer nearly universal means for detection of molecular substances and provide unique insights into elementary excitations in solids. The proposed S-SNIM will enable spectroscopy and imaging in the near/mid-IR region at cryogenic temperatures with spatial resolution down to 10 nanometers.
Broader impact: The proposed instrumentation will significantly impact the research infrastructures at the local, regional, and national levels. Locally, more than 25 grad students and researchers affiliated with 9 research groups at UCSD will enhance their training and research. Regionally, a number of industrial partners will gain access to the micro-spectroscopy instrument. Nationally, the proposed instrumentation will reduce burden on oversubscribed synchrotron beamlines at national laboratories, whereas the commercialization of these instruments in collaboration with Agilent and industrial partners will help to maintain the US leadership in manufacturing state-of-the-art instrumentation for probing matter at the nanoscale. Educational activities include development of a new special-topics course, opportunities for interdisciplinary education and training of underrepresented groups. This latter involves outreach to middle and high school students at the UCSD Preuss School, recruitment and mentoring of graduate students and post-doctoral scholars, as well as of undergraduates in conjunction with CAMP: California Alliance for Minority Participation.

Anderson's Devices: Using Disorder For Functionality in Photonics @ University of California-San Diego
The goal of this project is to develop a new class of photonic circuits and devices of large complexity, in which disorder can be harnessed and controlled, for use as reconfigurable optical buffers, switches, and wavelength converters. These silicon-based Anderson's devices will comprise hundreds of individual elements, such as resonators, couplers, sequential taps etc. Such large circuits represent an orders-of-magnitude advance in complexity from the state-of-the-art, and necessitate careful attention to the effects and remedies of disorder induced by imperfect lithography or computational limitations in the design process.
Intellectual merit: The major challenge addressed by this proposal is how to design for, test and demonstrate photonic devices which can withstand and even utilize disorder. The key of our approach lies in utilizing disorder for useful behavior, such as dynamically-controlled Anderson localization of light, or ultra-low energy nonlinear optical switching. This project may help bridge the gap between optical device engineering and condensed matter physics, and advance our understanding of the cooperative behavior of photons in lithographically patterned structures. These devices can be used for packet-length switches, delay lines, and a novel "Anderson optical memory".
Broader impact: The PI commits during this project to support the mentoring and career-development of a post-doctoral researcher. Educational activities include development of a new special-topics graduate-level course for which course materials will be prepared and made freely available on the internet, the PI will work on a textbook on Micro-resonators, and opportunities will be provided for interdisciplinary education and training of underrepresented groups.

Chip-Scale Classical and Quantum Nonlinear Photonic Mixers @ University of California-San Diego
The objective of this program is to develop a chip-scale technology for compact and efficient nonlinear classical and quantum photonic mixers while maintaining compatibility with silicon integrated optoelectronics. Proposed research builds on recent accomplishments of slow-light enhanced nonlinearity which is 20x higher than that of conventional silicon nanophotonic waveguides, correlated photon generation via spontaneous four-wave mixing in long chains of low loss coupled silicon microring resonator waveguides, and telecom-band to infrared four-wave mixing conversion in nitride-clad silicon waveguides. Devices will be designed, fabricated and measured which combine electro-optic functionality, materials engineering and lithographic patterning to substantially improve the figures of merit of nonlinear optical frequency conversion applications.
The intellectual merit is to develop chip-scale devices with orders-of-magnitude improvement in energy efficiency, and reduction in size, weight and cost, compared to fiber-based or crystal-based bulk nonlinear optical systems. Novel scientific insights will emerge from the systematic study of combined electro-optic and nonlinear optical phenomena in both the classical and quantum regime, bridging traditional barriers between those fields. The outcome of this project will be the creation of optoelectronic devices useful for data and free-space communication, chemical and biomolecular spectroscopy, sensing, metrology, cryptography, and quantum photonics.
The broader impacts are to integrate several modern scientific disciplines, to which graduate students will gain valuable exposure and benefit from research collaborations with industry and government laboratories which provide broader perspective and scope for field applications of the novel scientific breakthroughs.

Goali: Active and Nonlinear Silicon Photonics Using Hybrid Thin-Film Lithium-Niobate + Silicon @ University of California-San Diego
The objective of this research is to overcome fundamental performance limitations in today's lightwave communications devices by using a hybrid nanophotonic waveguide cross-section, consisting of a bonded stack of silicon and of a ferroelectric oxide, e.g., lithium niobate. The approach is that modulators and nonlinear optoelectronic devices will be fabricated using the hybrid material, formed by oxide thin films being transferred onto a planarized silicon photonic chip using a low-temperature plasma-assisted bonding process which preserves diodes and transistors in the silicon chip.
The intellectual merit of this proposal is to realize, via use of this hybrid material system, optoelectronic devices that perform beyond the possibility frontier of devices fabricated using either material system alone. In the context of silicon photonics, the project will demonstrate a robust and high nonlinearity without sacrificing high index contrast. The project will also demonstrate more complex waveguide structures than possible in conventional lithium niobate structures.
The broader impact of this proposal is firstly, to benefit the information-driven infrastructure needs of modern society by enabling faster data networks without increasing energy consumption. Secondly, this GOALI collaboration between a university and a small business, both having committed interest in this area of research, involves two-way researcher visits, and technology and knowledge transfer. Results from this collaboration will be published in peer-reviewed literature, will form components of graduate student thesis research, and will provide a roadmap to future commercialization by interested parties. The project also target opportunities for interdisciplinary education and training of underrepresented groups.

Nets: Small: Can Disaggregation and Silicon Optical Interconnect Technology Co-Exist? @ University of California-San Diego
About one hundred billion data packets (equivalent to a few thousand Encyclopedia Brittanicas) are transmitted every second from a typical office building. Bottlenecks or breakdowns in modern communication networks instantly impact air travel, healthcare, financial markets, education and entertainment, and national security - in short, every aspect of modern life. To increase bandwidth for the coming decade without commensurately increasing energy consumption, engineers are now using photons (light) rather than electrons (voltage) to carry data between computers. In the near future, photonics may also be used to communicate between microchips inside computers, or between microprocessors and memory. This project addresses a emerging research challenge in ensuring the scalability, control and effective management of massive optically-connected networks such as warehouse-sized data centers.
Disaggregation replaces motherboard bus architecures with communication networks such as Infiniband and PCIe, thus enabling scalability and controllability, but requires the network to deal with new types of data flows that span several orders of magnitude in bandwidth and latency requirements. These requirements are not compatible with the type of silicon photonic chips that have been designed so far. This project will use silicon photonics to more effectively enable disaggregation within data centers; leveraging key strengths of optical communications compared to traditional electronic wires: the ability of light of different colors to pass through each other without interference, thus enabling different logical interconnections in a network across the same physical network topology. To test and develop this concept, silicon photonic microchips will be designed and fabricated in collaboration with industry and/or government organizations that host silicon photonic foundry resources. The performance of these innovative communication chipsets will be studied in a optical networking testbed.

Efri Acquire: Microchip Photonic Devices For Quantum Communication Over Fiber @ University of California-San Diego
Abstract title: Microchip Photonic Devices for Quantum Communication over Fiber
Abstract:
Conventional computers and communication networks are encountering stringent limits on performance and scalability. There is an increasing need to reduce the energy costs of data processing, storage and communications, as well as for guaranteed security and authentication in both communication and computation systems. Quantum technologies offer a viable "Beyond-Moore's-Law" strategy, especially in communications and information processing, where quantum optics has clearly demonstrated beyond-classical advantages in a number of landmark experiments. But the traditional approach of quantum optics relies on table-top laboratory experiments usually conducted at extremely low temperatures, and requiring large and expensive ancillary equipment for successful operation. These constraints inhibit the transition of quantum optics research into practical applications and everyday usage. This project will use the same technology as used to make integrated circuits in the electronics industry today to develop a new generation of energy-efficient, non-cryogenically cooled microchips for secure and efficient optical communications. Development of these microchips will also benefit sensors and standards calibration, metrology, and low-light-level imaging. The transition of laboratory research to real-world applications will be helped by leveraging scalable and cost-effective foundry-based manufacturing technologies to make devices. Research collaborations with industry and government laboratories will provide broader perspective as well as scope for field applications and student mentoring. The project will also support the development and dissemination of educational modules that introduce quantum mechanics through optics for high schools (including material for laboratory experiments) and undergraduate students, including future engineers who traditionally have not learnt about quantum mechanics and its potential engineering applications.
The technical goal of this project is to design, fabricate and demonstrate microchips for quantum communications using entanglement over conventional optical fiber. Research will focus on creating ultra-compact (centimeter-scale) microchips which miniaturize previous table-top or bread-board apparatus for generating and detecting entangled, heralded and single photons, for quantum memories without requiring cryogenic cooling, and for demonstrations of quantum key distribution protocols. Scalable manufacturing techniques based on established micro-electronics foundry platforms will be utilized, which may result in reducing the cost and mitigating some of the risks of making greater quantities of devices for practical applications. Integrated pair-generation and single photon devices will be designed for encoding time-bin information with gigahertz-rate clocking. Key linear optical quantum information processing devices will be designed, such as up-conversion devices, uncooled waveguide-coupled quantum memory using storage and retrieval of photons, and an electro-optically switched recirculating loop which combines both planar and fiber technology and enables synchronization of photons over long relative delays. Microchips will be characterized in a fiber-based testbed for demonstrating the protocol of measurement device independent quantum key distribution. Many of these components and measurements will be also useful for a future fully-integrated quantum repeater in optically connected communication networks.
