This Phase I project has two primary objectives. The first objective is to evaluate the feasibility of a fully ion implanted fabrication process based on the heterodimensional 2-D MESFET. The new device, the 2-D JFET, will have p+ ion implanted sidegates which laterally modulate a thin, highly doped n-type conducting channel. The 2-D JFET should have excellent high speed, low power characteristics ...

A novel quantum well infrared photo transistor, which we call QWIPT, is proposed. By taking the advantage of the almost perfect alignment of the conduction band in GaAsSb/InAlAs system, it is possible to integrate such quantum wells into a QWIPT to improve the optical gain and, therefore, the detectivity of the p-QWIP. We expect, by incorporating molecular beam epitaxy growth interruption scheme, ...

A THEORETICAL PROGRAM IS PROPOSED TO INVESTIGATE A COMPACT, LOW-VOLTAGE INFRARED GRATING LASER WITH MULTI-KILOWATT OUPUT CAPABILITY. THE RADIATION IS GENERATED BY THE PASSAGE OF AN ANNULAR BEAM OF ELECTRONS THROUGH A COAXIAL PAIR OF CONDUCTORS, THE INNER CONDUCTOR BEING A CORRUGATED CYLINDER WHICH FORMS THE GRATING. THE ELECTRON BEAM IS GUIDED BY AN AXIAL MAGNETIC FIELD. THE DIMENSIONS OF THE OPTI ...

This proposal suggests that a basic data collection, management, and fusion framework is ideally suited for integrating distributed data from multiple heterogeneous sources and making it available on a multi-point basis for analysis, viewing, and C**4I applications. The basic framework proposed was built (and is currently under ongoing development) to support object-oriented, temporally consistent ...

This program will demonstrate key enabling technologies for Terabit/second optical fiber networks capable of meeting critical DoD needs. Optical network technology offers characteristics that satisfy many DoD requirements. These characteristics include improved data handling through multiwavelength transmission in single optical fibers; enhanced network security; greater inter-network operabilit ...

MANY CURRENT AND PLANNED DEFENSE AEROSPACE PROGRAMS DEPEND CRITICALLY UPON RAPID DEVELOPMENT OF LIGHTWEIGHT COMPOSITE MATERIALS HAVING UNPRECEDENTED HIGH-TEMPERATURE PROPERTIES. CONTINUOUS FIBER REINFORCED INTERMETALLIC MATRIX COMPOSITES (IMC'S) HAVE THE POTENTIAL TO MEET THESE PERFORMANCE REQUIREMENTS, AND CONSIDERABLE RESEARCH EFFORT IS NOW DEVOTED TO DEVELOPING THEM. WE RECENTLY DEMONSTRATED A ...
