A proposed OEIC receiver using MESFET photodetector

An optical receiver configuration based on the concept of using a single op tically gated metal-semiconductor-field-effect transistor (MESFET) to perfo rm the function of a photodetector and preamplifier has been introduced. Th e proposed optoelectronic integrated circuit (OEIC) receiver has been analy zed theoretically. A simplified noise model of the receiver has also been d eveloped, Results have been presented for an OEIC receiver based on InGaAs MESFET supposed to be Fabricated with matured InGaAs/InP MMIC technology. T heoretical results based on a simplistic noise model reveal that the propos ed OEIC receiver has superior performance characteristics over the existing optical receivers.
