In the proposed effort, we will leverage this extensive experience and capabilities to realize a frequency agile mmW radiometer that can cover the range of DC-110 GHz and can be scaled to DC-200 GHz under Phase II. Ours is a photonic system that multiplies and up-coverts a low-frequency reference signal onto an optical carrier (laser) using EO modulation, then uses the modulation sidebands to inj ...

The Phase I Project will develop a comprehensive model to evaluate and optimize state-of-the-art light-emitting diodes for optical memories, optical computing, and fiber or free-space photonic interconnects. The innovation is the development of resonant optical cavity LEDs and a proprietary low-cost epitaxy technology for their fabrication. A unified approach to the design of LEDs with resonant op ...

There is a need for optical materials with large nonlinear coefficients and high laser damage thresholds for tunable laser operation in the 2-5um region. This proposal describes a new member of the KTP family CsZrOAsO4 (CZA), which is expected to have superior properties in comparison to KTP. An empirical relationship between nonlinear properties and dielectric molecular polarizability indicates t ...

Bipropellant Systems usually contain isolation valves feeding banks of thruster valves downstream of the propellant supply tanks. Thruster valve problems, when occurring in operation, could cause isolation valve closure, disabling the remaining "operable" thruster in the thruster bank. Marotta proposes to develop an innovative, unique solenoid valve that integrates both the isolation and thruster ...

Phase I will investigate the feasibility of developing a novel class of very high capacitance per unit volume capacitors. It is expected to produce capacitances of Farads in volumes usually limited to micro Farads without the low voltage, low current limitations of many electrolytic types. Because energy stored is proportional to the product of capacitance times the square of the voltage, our conc ...

An InGaAs/InP based laser structure is proposed based on a novel approach for truly continuous wavelength tuning over a wide range with negligible power dissipation associated with the laser tuning. The laser structure will be grown by MOCVD and fabricated into a tunable laser with an initial tuning range up to 70 A in Phase I. Once we demonstrate the concept, a widely and truly continuously tunab ...
