Degenerate mode of operation in photoparametric amplifying devices

The photoparametric mode of operation involves optical detection and pre-amplification / frequency conversion within a single device (a photodetector). In this paper, we will report to the conference the results achieved by operating the amplifier in degenerate mode. In this particular mode of operation the gain is considerably higher than up or down conversion modes which has been reported earlier. The device structure, its characteristics and amplifier simulation techniques will be presented. Experimental results from implementation of a prototype receiver are discussed.
