As complexity and performance requirements increases for RF sensors and systems for electronic warfare applications, the need for innovative and low-power compressive sensing (CS) technologies will become urgent in power constrained mobile platforms. There are several DOD and government application areas where this holds true and the high-performance CS technology to be developed in this program c ...

Users of additive manufacturing machines expect the highest quality when it comes to the mechanical properties of parts, the usability of the machines and associated processes, and overall machine design. The main contributor to the quality of the part is the involvement of process-related by-products originating from the melting process. To handle these by-products in additive manufacturing - in ...

We propose to develop tunable, high-power handling, low-loss phase-to-amplitude conversion photonic-integrated circuit (PIC) based device on heterogeneous SiN platform. The use of SiN for waveguide is the key to meet the stringent requirements, while additional heterogeneously integrated components are the key to enable tuning and locking of the phase-to-amplitude device. Nexus Photonics, realizi ...

We propose a serially concatenated switchable asymmetric Mach Zehnder switching network on a silicon nitride photonic integrated circuit platform to provide flexible and switchable demodulation of signals from less than 1 GHz to greater than 45 GHz. The silicon nitride platform provides a low size weight and power solution while reducing the stabilization requirements and providing long path lengt ...

Quantum Cascade Lasers (QCLs) are one of the most versatile sources of radiation in the mid-infrared range and have found applications in a variety of fields. Despite their widespread adoption, one of the main hurdles holding QCLs back from large volume manufacturing is the large cost of ownership. While QCLs, like most semiconductor devices based on III-V compounds, can leverage the economies of ...

As modern-day ships require more advanced applications and systems to run directly on the vessel, they require large amounts of computational resources to execute the complex software and algorithms.  While these next generation capabilities provide immense value, the downside is that now the compute servers and clusters required to support these capabilities become single points of failure. To c ...

Advanced sensors and effectors are driving shipboard power distribution systems toward higher voltages, resulting in greater thermal demands on the power conversion modules.  Wide Bandgap (WBG) semiconductors, such as silicon carbide (SiC) and gallium nitride (GaN), can be utilized to reduce thermal inefficiencies with high-frequency switching topologies, but heat generation is still a primary li ...

We propose the novel approach of using chaotic micro-resonators on photonic integrated circuits to reduce the size, weight, and power (SWaP) and increase the stability of the random basis generation portion of a compressive sensing system with the goal of enabling a large bandwidth radio frequency (RF) receiver while reducing the requirements on data capture. Our proposed technical and programmati ...

Intelligent Optical Systems, Inc., in collaboration with Bowling Green State University, proposes to develop a field-rugged, eye-readable indicating spray solution that can immediately detect synthetic opioids over a large area of contamination (i.e., military vehicles, individual protective equipment, clandestine labs, etc.). The proposed chemosensor in a spray solution format will detect multipl ...

Raytum Photonics teams with the Center for Advanced Life Cycle Engineering (CALCE) of University of Maryland in order to come up with an efficient burn-in process to effectively screen out infant mortality and accurately predict life time for QCL lasers in shortest possible time.   The proposed burn-in process is based on an accelerated degradation model which speeds up the burn-in process by el ...
