Passive broadband limiter with high response speed is a promising device used to protect optical sensor against determined attack. Lam Optics, Inc. (LOI) proposes to investigate the development of a novel optical limiter using commercially available materials. The optical limiter operates on the following principles. These are beam self-defocusing and total internal reflection induced by absorptio ...

Design and fabrication of a high thermal conductivity carbon fiber/aluminum matrix composite architecture is proposed which consists of discrete segments of functional areas that can respond to complex design calling for thermal management, low-expansion, structural, and low specific weight requirements. Composites will be produced utilizing Hollow and Planar Cathode Magnetron Sputtering Processin ...

Photorefractive materials promise to enable dynamic holography and erasable high density data storage for future information technologies. This project will develop and demonstrate a holographic data storage technology using novel photorefractive polymers with electro-optic (EO) coefficients and bandwidths that are significantly superior than LiNbO3. An important advantage of these polymers is tha ...

The application of high-temperature refractory materials such as rhenium, iridium and tungsten to liquid rocket engines holds substantial potential for improvement in the life of the components. Currently, Ir-Re rocket engines and thrusters are manufactured by chemical vapor deposition. Although this technique has been successful, it is plagued by prohibitively high costs and low rate of product ...

The objective of this Phase I is to develop a high quality, high speed, cost effective technique for polishing silicon carbide mirrors that are machined using single point diamond turning methods. The finished optic should have a more perfectly polished surface with uniform shape and thickness than is presently being produced. We will achieve this by using two different approaches, a novel non-con ...

We propose to develop a novel and ambitious tool for large-scale development: a fourth-generation computer language (4GL) based upon an object-oriented generalization of the hierarchical block diagram paradigm, with powerful integrated simulation capabilities. Developers would assemble a prototype in a connect-the-blocks visual programming environment, test and evaluate it via simulation, then ite ...

We propose a systematic investigation of crystalline Si structures as their dimensions are reduced to quantum sizes (5-10 nm). For convenience, we have chosen Si on insulator (SOI) material for optical and electrical characterization. Our nanofabrication approach relies on simple laser interferometric lithography techniques that are uniquely adaptable to large area manufacturing. Suitable applic ...
