ABSTRACT: In this STTR effort a small business company Obalon LLC is teaming up with industry leader Aerospace Corporation for development of novel photostructural glass ceramic composition (PhotoCon) with capability of laser induced 3D conductor patterning inside the bulk material. The development fully utilizes available infrastructure and team's expertise for commercial glass ceramics pro ...

The increasing use of video in force protection, autonomous vehicles reconnaissance, and surveillance in general has created a great demand for automated analysis and monitoring. It is infeasible to have humans monitoring and analyzing the vast amount of video used in such surveillance, and automated analysis yields hope to ease the burden and increase the amount of information extracted from col ...

ABSTRACT: Optical refrigeration is currently the only demonstrated all-solid-state cryocooling technology. Optical cryocoolers are devices that use laser light to cool small crystal or glass cooling elements. The cooling element absorbs the laser light and reradiates it at higher energy, an example of anti-Stokes fluorescence. The difference between the energy of the outgoing and incoming light c ...

Multi-processor computing systems are growing in capacity and usage. They encompass multiple, distributed implementations as well as heterogeneous, embedded computing architectures. The processing density enabled by such approaches holds promise for unmanned combat air vehicles (UCAVs) with their plethora of mission sensors and command and control processing requirements. However, the software ...

The development of compact, ultra-low drive voltage optical phase modulators is a critical key component for passive antenna remoting applications, a strategic area, part of a number of current and upcoming DARPA initiatives. With the development of sufficiently low V-pi modulators, passive front-ends can be constructed with a low figure even for a moderate optical pumping power. The combination o ...

Aerius Photonics is proposing to develop high-power Vertical Cavity Surface Emitting Lasers (VCSELs) and arrays on 4” substrates with an integrated thermal management approach to improve the thermal performance on an entirely wafer-level manufacturing compatible process. This is critical as waste heat and wafer-scale manufacturing approaches are driving factors for performance and costs in a la ...

Cost effective semiconductor processing tools that enable the high-resolution nano-fabrication of low-volume electronics are needed by the DOD. The printing of ultra-fine gratings on silicon wafers using interference immersion lithography is envisaged as a first maskless process step in the fabrication of advanced application specific integrated circuits. Next generation interference immersion lit ...
