A back-illuminated planar InGaAs photodiode tested to have 95% quantum effiiency (QE) at 1550 nm, area greater than 1 mm2, low capacitance (125 MHz) will be improved. Although the existing Phase I device exhibited bulk material dark current generation better than commercially available devices, the sidewall-generated dark current was found to dominate the noise equiva ...

This proposal is for the development of a technology apparatus which can dynamically synthesize a mechanical fingerprint pattern, from an electronic image or from a computer-generated artificial pattern, onto a 2-dimensional pliable surface whose surface height is modulated by protrusions in the z-axis direction. When mechanically applied to a fingerprint sensor-under-test, the synthesized modulat ...

Conversion of highly stable optical clocks into electrical clocks through photodetection introduces excess phase noise, thereby degrading the frequency stability. This noise is primarily generated due to the conversion of optical intensity noise into electrical phase noise by photodiode¿s non-linearity, specifically power-to-phase conversion. During Phase I, Discovery developed dual photodiodes h ...

Even today as a highly technical and advanced world civilization, the physiology of deep sea fish and invertebrates continues to remain mysterious and poorly known. Past specimen containers fail to either have the size or volume needed or lack the robustness for high pressure containment of in many cases, lack the repeatability necessary to ensure a reasonable lifetime of continuous use. The Tec ...

Voxtel has demonstrated efficient high-speed photon counting with thresholded linear-mode avalanche photodiode (APD) receivers using multi-gain-stage InGaAs/InAIAs APDs. In contrast to Geiger APDs, thresholded photon-counting linear APD receivers are thought not to suffer afterpulsing, and can support maximum count rates (MCR) up to 2 or 3 orders of magnitude faster than Geiger APDs. However, the ...

Spiny lobster, Panulirus argus, aquaculture on a global scale is a small fraction of the total annual wild harvest. The ability to advance the culture of spiny lobsters will reduce the stress on the natural stock while providing a highly desired product. The culture cycle is dependent on the collection of lobster pueruli from the wild, due to the difficulty in rearing the larvae through the year ...
