The rapid advance in optical clocks and oscillators calls for similar advances in free-space frequency/time transfer. I will discuss our frequency-comb based system for coherent optical transfer of time and frequency over free-space links with femtosecond level stabilities and with robustness to atmospheric turbulence.

Infrared imaging (3-25μm) has been an important technological tool for the past sixty years since the first report of infrared detectors in 1950s. The ability to detect the temperature of a scene from the blackbody radiation that it emits has spawned applications in a wide variety of fields ranging from defense and security to non-invasive medical diagnostics and remote sensing. However, IR imaging landscape has dramatically changed in the past decade. Firstly, the cost of lower end imagers has been steadily declining (30% every year since 2005) enabling them to be mounted on dashboards of automobiles including Audis and BMWs. Secondly, advent of novel antimonide based semiconductor technology has dramatically improved the performance of higher end imagers that are used for military, defense and security applications. There has been a dramatic progress in the development of infrared detectors in the past decade with new materials like InAsSb, InAs/GaSb superlattices and InAs/InAsSb superlattices. However, in spite of dramatic technological progress, there are a lot of unknowns in these materials. For instance, the background concentration, vertical mobility, diffusion constants etc for these systems are largely unknown or are very difficult to measure accurately. The GaSb conducting substrate coupled with anisotropic transport and quantum transport makes the investigating of this system challenging.

Free-space optical networks have serious block erasures due to atmospheric turbulence and require an entirely new network architecture from Layer 1 to Layer 4 for big data flows.

The National Network for Manufacturing Innovation (NNMI) is a network of research institutes in the United States that focus on developing and commercializing manufacturing technologies through public-private partnerships between U.S. industry, universities, and federal government agencies. The newest Institute was announced July 27, 2015: The American Institute for Manufacturing Integrated Photonics (AIM Photonics). This Institute is focused on developing an end-to-end photonic integrated circuit (PIC) ecosystem in the U.S., including domestic foundry access, integrated design tools, automated packaging, assembly and test, and workforce development. The Institute will develop and demonstrate innovative manufacturing technologies for: 1) Ultra-high-speed transmission and switching of signals for the Internet and telecommunications 2) Microwave photonic PICs 3) Multi-sensor applications including chem-bio sensors, urban navigation, and other topics The AIM vision is to establish a technology, business and education framework for industry, government and academia to accelerate the transition of integrated photonic solutions from innovation to manufacturing-ready deployment in systems spanning commercial and defense applications. Silicon photonics has the potential to significantly reduce the cost of optical devices used in many traditional applications in addition to enabling new devices and applications. This is because of the maturity of CMOS processing facilities and infrastructure and because of the capabilities and efficiency of photonic integration. The ability to integrate photonic devices with CMOS electronics in a wafer scale manner can greatly increase the capacity of integrated circuits and reduce the size, weight, power dissipation while simultaneously increasing the reliability of the systems employing these components. The low loss of silicon waveguides enables large, complex passive components to be made without significant signal attenuation. It also improves the performance of lasers, resulting in lower thresholds and narrower linewidths. AIM Photonics provides a variety of solutions for integrating the critical functionality of III-V materials, ranging from monolithic InP PICs to heterogeneous materials integration. This presentation will summarize the AIM Photonics Institute and over 50 partners participating in the Institute. It will summarize the impact AIM Photonics can have on the Avionics community and ways for industrial, government and academic users to use the foundry and other services in AIM Photonics.

A high performance liquid-level sensor based on microstructured polymer optical fiber Bragg grating (mPOFBG) array sensors is reported in detail. The sensor sensitivity is found to be 98pm/cm of liquid, enhanced by more than a factor of 9 compared to a reported silica fiber-based sensor.
