Develop and package a 2 x 2 single mode optical switch operating at 1.55 µm wavelength capable of switching speeds below 1 µs with a directivity of 50 dB and an excess loss of less than 1.0 dB with a continuous intensity change from port-to-port for routing RF/analog signals via singlemode fibers to different locations within the NAVY airframe. The optical switches must be low SWaP and capable o ...

The goal is to develop a tunable differential interferometer for wideband phase-to-amplitude conversion. The device must have high-optical power handling (> 300 mW) and low loss (< 3 dB) to ensure the creation of low-noise figure, high-dynamic range RF-over-fiber links. The device should operate over a -40°C to +85°C operational temperature range, and be tunable to cover phase-to-amplitude conve ...

While AI-based techniques have been broadly embraced by transportation researchers and professionals due to their huge potential to significantly improve the efficiency and accuracy of analyzing transportation data, they typically require a large dataset to train the models effectively and experience difficulties in supporting real-time transportation operations and management. This project will u ...

EOSPACE proposes to develop a widely applicable supporting optical circuit in micro-optics that will provide bidirectional optical monitoring using dual photodetectors. The final circuit will be capable of surviving shock, vibration, and thermal excursions typical of aircraft or missile flight.

American Energy Technologies Company, a woman-owned small business concern out of Arlington Heights, Illinois will conduct the modeling, technology development and prototyping of the specialized carbon-based ram jet nozzle inserts aimed at maximizing the combustion performance of new-generation solid rocket fuels. The primary objective of the inserts will be to prevent condensation of oxide phase ...

The goal of this proposed Phase II effort is to design and demonstrate a monolithic architecture for two-dimensional, all-electronic beam steering of a high power, mid-infrared laser. A photonic integrated circuit architecture is described which contains a widely tunable, mid-infrared quantum cascade laser integrated with a phase-adjustable amplifier array and a high efficiency grating outcoupler. ...

Type II superlattices (T2SL) represent a promising material system capable of delivering very producible, large-format broadband MWIR and LWIR focal plane arrays (FPAs). High temperature operation of current MCT based FPAs is limited by inherent defects in the II-VI material and strong Auger recombination. T2SLs are based upon mature III-V materials and would provide high material quality, lower s ...

A Free Space Optical Communication Systems (FSOCS) enables broadband inter-connectivity among mobile platforms.  A key feature of an FSOCS is the low probability of intercept and the low probability of detection (LPI-LPD).  Furthermore, it is unhindered by RF jamming or frequency contention.   When augmented by a passive range detection capability, it also enables precise location knowledge, a ...

The U.S. Navy seeks methods to improve the fuel economy of marine diesel engines through utilization of waste heat. Low temperature engine jacket water, lubrication oil, and aftercooler air are largely untapped streams of thermal energy on these ships, but their utilization circumvents many operation challenges associated with exhaust gases. For example, variable and high exhaust gas temperatures ...

Metal-organic frameworks (MOFs) are advanced adsorbents with applicability to military and civilian applications including but not limited to chemical biological protection, chemical warfare agent decontamination, toxic industrial chemical remediation, medical oxygen delivery, and energy storage. These materials have been produced in ton-scale quantities and have seen commercial use in the electro ...
