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 SBIR Phase II project proposes to add telemetry and monitoring equipment to the spar designed and constructed under our Phase I contract. Furthermore, we propose to test and evaluate an automated spar feeding system suitable for use on an operating offshore fish farm. C Cates International, Inc. has developed a feeding system for it¿s underwater cages that functions from a small boat. But ...

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 ...

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 ...
