Photonic devices providing high performance spectral filtering, multiplexing, optical waveform processing, and signal routing will be designed, fabricated, and characterized. The devices are based on photolithographic scribing of holographic structures onto the surface of planar waveguides and operate on intra-guide signals. The holographic structures provide a manufacturable approach to 2D phot ...

Special Operation Forces personnel require a rugged, miniature receiver that is capable of monitoring RF energy while deployed on a mission. The RF receiver will give a better picture of the electromagnetic threat environment enabling a heightened situational awareness, yet the device must be small enough that it does not hamper the SOF warfighter during missions requiring stealth and rapid mobil ...

This project is designed to test a novel receptor scaffold/sensor combination for the selective and direct measurement of antigens and to compare direct electric detection of antigens against the corresponding antibody based ELISA method. The scaffold concept combines a robust nucleic acid receptor (aptamer) coupled to a low cost CMOS FET and AlGaN MODFET transducer. Aptamers are short nucleic aci ...

The development of highly reliable, very high speed telemetry systems is critical for improving the capability of ballistic missile defense (BMD) systems. The objective of this project is to continue the development of telemetry radios based on m-ary variable shift keying (MVSK) technology, which offers more robust performance, exceptional immunity to interference (including intentional jamming), ...

In this Phase II SBIR program, Voxtel, Inc. will execute a design of experiments (DOE) to optimize the architecture and processes required to robustly manufacture, with high yields, a high performance radiation-hard, silicon-on-insulator complimentary metal-oxide-semiconductor (SOI CMOS) imager that meets the requirements of the Radiation-Hardened Star Tracker for future space-based defense system ...

In this Phase II SBIR program, Voxtel will design, manufacture, and test a 32 by 32 element, 30-micron pitch, 1064-nm optimized Geiger Mode (GM) avalanche photodiode (APD) array. The array will be electrically and optically characterized and will be tested for total dose radiation performance. The innovation is significant in that there currently are no APD/ROIC focal plane assemblies that have a ...

In this Phase I SBIR program, Voxtel, Inc. proposes to develop a novel focal plane technology aimed at enhancing the passive and active ground-based, deep space surveillance and tracking of multiple targets in real-time. To increase the performance and functionality of tracking focal plane arrays, we have designed a monolithic, deep-depletion, SOI CMOS imager, with low noise. On-chip functions inc ...

Voxtel, Inc. proposes to optimize the design of a 1.00-µm to 1.55-µm near infrared (NIR) linear mode (LM)HgCdTe avalanche photodiode (APD) array that achieves high gain with nearly no excess noise, so as to achieve high bandwidth (e.g. > 1 GHz) single photon counting laser radar (LADAR) operation. Leveraging the low noise LM avalanche gain and our low noise CMOS LADAR receiver circuitry, we wil ...
