Opto-EM and Devices Investigation
Abstract
This report is composed of seven sections. It provides a summary of work accomplished under this contract in several diverse areas of optical transmission, materials processing. The areas include: A description is given of the experimental program on the synthesis and single crystal growth of indium phosphide. Device processing techniques covering the use of ultra high vacuum deposition system for evaporating a dielectric layer of silicon monoxide. Materials evaluation techniques under the general heading of electron microscopy. A description is given regarding connecting a two-hidden-layer neural network through an intermediate multiplicative layer showing that it can yield full or partial disambiguities of results from a single 'traditional' neural network. Communication security has been achieved in fiber optic communication systems (IROCS) by ensuring that any undetected intrusion will deliver so little power to a potential intruder that no useful information can be extracted from it. Photorefractive and resonant nonlinear optical interactions are being studied, and In this report the requirements of nonlinear optical materials are discussed and fundamental limits are derived.
