"A method for generating a high power, continuous wave (cw) monolithic micro-laser with rapidly tunable, narrow linewidth output is proposed. The concept employs a semiconductor laser coupled to an electro-optically controlled Bragg waveguide in PotassiumTitanyl Phosphate (KTP) providing single frequency output. Frequency tuning is achieved by applying a voltage across the waveguide, thereby cha ...

DESIGN AND FABRICATION OF SOLID-STATE DIRECTION-INDICATING APPARATUS, WITH TILT-IMMUNITY, THAT PROVIDES AN AUDIBLE OR TACTILE INTERFACE WITH THE USER. REDUCED SIZE TO ALLOW ENCAPSULATION IN A TYPICAL WALKING CANE. A DEVICE WILL BE DESIGNED THAT WILL PROVIDE A VISUALLY IMPAIRED PERSON WITH AN INDICATION OF HORIZONTAL DIRECTION, WITH RESPECT TO THE EARTH'S MAGNETIC FIELD. THE DEVICE WILLALSO SIGNAL ...

"The proposed high bandwidth electro-optic modulator uses an optical waveguide microcavity to enhance the interaction of optical fields with a material that exhibits coherent quantum attributes. The nonlinear characteristic of the light - matter coupling inconcert with the resonance requirements of the microcavity provide a sensitive modulation mechanism. In the device the combination of nanophoto ...

"Much of the focus of the ATR effort has focused on target definition within a test site. Synthetic Aperture Radar (SAR) has demonstrated great potential to precisely identify metal-based targets under precise conditions. Though SAR excels in this area,it is far less useful for predicting vegetative, geologic and non-metallic anthropogenic confusion, the forte of hyperspectral data. Using hyper ...

For this Phase II proposal, Space Photonics puts forth highly innovative solutions for multi-access spacecraft clusters using our proposed miniature modular free space laser communications transceiver subsystem. Our innovation uses MEMs technology todirect and acquire laser crosslink signals. This eliminates the need for the large, power hungry, mechanical gimbals previously required for laser cr ...

"Complex analysis of intelligence imagery is crucial to the missions of intelligence organizations, yet remains constrained by labor-intensive, time-consuming visual search of large volumes of imagery. Many algorithms have been developed to automaticallyidentify regions of interest in large, complex sets of imagery, yet the utility of such algorithms is limited by the fact that human analysts dete ...

The proposed work includes both laboratory analysis of coated coupons and field diagnostics of aircraft. Laboratory aging of multiple coating systems will be conducted under various aging cycles with the effects of fluid exposure (wash fluid, de-ice,etc.) included. Failure analysis of coupons will be correlated with on-aircraft measurements. A predictive model for coating life will be tuned and ...
