LOW RISK ILLICIT DRUG LEVEL MONITORING

Not Available This proposal concerns the development of a large area, high speed infrared sensitive photodetector with wide dynamic range and high gain needed for the development of microwave modulated lidar systems operating at near-infrared (NIR) wavelengths of >1 micron. The project will be in collaboration with two manufacturing partners. This strategy should provide the fastest and most cost-effective technical and commercial success. The proposed photodetector is based on vacuum phototube technology with an active area of 1 mm2, gain of greater than 1000, and a bandwidth of 5 GHz which far exceeds the performance of commercially available large area NIR photodetectors. In Phase I we will develop a computer model of the NIR photodetector and devise a complete set of device fabrication and characterization processes. Phase I will show the feasibility of achieving superior performance. The proprietary design is described in the full proposal. The Phase II objective will be the fabrication of an optimally designed prototype device and the subsequent performance characterization. Phase II will demonstrate that this prototype provides superior sensor performance and will also address the manufacturing process to produce the highest device fabrication yield enabling successful Phase III commercialization.
