APA Optics will develop a monolithic UV seeker for use in flame sensing and passive or tactical threat warning systems. The key to the technical approach is the deposition of high optical/electrical quality Al(x)Ga(1-x)N over GaAs substrates and using it to fabricate back to back Schottky barrier detectors. Al(x)Ga(1-x)N is a compound III/V semiconductor system with a bandgap tunable from 220 to 3 ...

High voltage semiconductor devices have found important applications in the areas of high power generation, power control, power conversion, surge protection, and industrial electronics. However, GaAs or Si based high voltage device are limited by a relatively low intrinsic breakdown voltage and,therefore, inherently suited for high power applications. We propose to develop novel high voltage hete ...

There is a serious need for new types of position sensors for use with adaptive optics systems which employ segmented mirrors. In particular, sensors which enable the system to control and maintain the phase matching of the mirrored surfaces of adjacent segments to accuracies of a few nanometers are needed. Blue Line Engineering Co. proposes to develop a novel type of sensor which will be suitable ...

Cryogenic radiometers are the primary standards for the measurement of power in the infrared, the visible, and the ultraviolet, a large part of the ueful spectrum. The integrity of the DoD procurement process and of DoD technology development depend critically on these standards. One aspect of this dependence is measuring the characteristics of those devices that work well in battle. Those measure ...

Combustion chemical vapor deposition (CCVD), which was invented by the principal investigator, is a high quality film deposition technique that can inexpensively and quickly apply lead zirconate-titanate (PZT) thin films in a continuos manner. This technology can be used for the production of ferroelectric capacitors. CCVD is low cost, high quality and versatile. It does not require a reaction cha ...

High power diode-pumped 2 micron lasers are of great interest for a variety of lidar applications, including long range hard target tracking and space-based coherent laser radar systems operating in the eye-safe region of the spectrum. Lidar modeling suggests that 0.5-1 J/pulse energies at pulse repetition frequencies of about 40 Hz will be sufficient to meet many lidar mission requirements. CTI h ...

We have devised a new type of "intelligent" optical fiber receiver able to tolerate inevitably time-varying wavelength shifted data. This robust optical fiber receiver will make WDM high-performance data transfer systems and even systems designed to operate in harsh environments very economical. The proposed receiver, which is also manufacturable and robust, is a suitable component for both packet ...

Many optical computing problems are centered around the processing of incoherent images. These images may be conventional visible light such as those taken with a CCD imager or camcorder. They may also take the form of infrared images in the case of missle seekers or x-ray images from medical or other sources. For optical processing, these images must be converted to either phase or amplitude modu ...

Null Convention Logic is a revolutionary new approach to digital circuits which replaces Boolean logic and provides a complete and general solution to practical speed independent logic circuits and systems. It is fundamentally different from Boolean logic, integrating data processing and control in ways that Boolean logic for electronic implementation (e.g. simple gates, etc.). It is expressed as ...
