THE OBJECTIVE IS TO DEVELOP A MULTIPLE WAVELENGTH LASER DIODE BASED ON QUANTUM WELL TECHNOLOGY. THE DEVICE IS BASED ON GALLIUM INDIUM ARSENIC PHOSPHIDE ON AN INDIUM PHOSPHIDE SUBSTRATE. THE MATERIAL COMPOSITION IS TO BE DETERMINED ACCORDING TO THE FORMULA OF 1-X AND 1-Y FOR ALL VALUES OF X AND Y LESS THAN 1.0. THE OBJECTIVE IS TO IDENTIFY MATERIALS WHICH WILL PRODUCE SPECIFIC OUTPUT WAVELENGTHS BE ...

DARPA HAS IDENTIFIED A NEED FOR NEW AND IMPROVED TECHNIQUES FOR COATING CERAMIC FIBERS FOR SUBSEQUENT INCORPORATION INTO METALLIC, CERAMIC OR HYBRID MATRICES. AMERICAN MATRIX, INC.'S PHASE I PROGRAM ADDRESSES THE SIGNIFICANT PERFORMANCE ATTRIBUTES (DEFINED BY DARPA AS INTERFACE CHEMICAL REACTION INHIBITION, INTERFACE BOND DEVELOPMENT,AND TAILORED PROPERTIES) WITH A MULTI-FACETED COATING PROGRAM.

Improved magnetic and electromagnetic sensors covering a wide range of frequencies, 0 to 10kHz, and with extremely high sensitivity are proposed for broad area detection and characterization of underground targets. The sensors can be used for a variety of applications and for different e.m. sources. They can be configured as gradiometers, as vector or scaler sensors and can be used as internette ...

The Department of Defense has undertaken an ambitious environmental restoration program at thousands of facilities in the U.S. Many of these facilities have been contaminated by the discharge of dissolved heavy metals. Often these contaminants migrate into the ground water where they pose a serious threat to aquatic systems and to human health. The remediation of soils and ground water is usual ...

Development is proposed for a breakthrough technique involving the use of electro-magnetic radiation to detect and measure thickness of non-conductive coatings on both metallic and non-metallic surfaces. The primary objective of the Phase I effort will be to prove that this approach can detect all forms of ice on aircraft structures and roadway surfaces. This system would permit detection and meas ...

A research and development program is proposed for developing and implementing a low temperature, highly anisotropic, reliable, environmentally benign reactive ion etching (RIE) for complex-oxide films. The RIE Process will be optimized such that it is highly selective (e.g., >5), with high etch rates (e.g., >50 nm/min) and there i minimal or no damage to underlying layers. Furthermore, effort wil ...
