A new technique for designing high-performance monolithically integrated In/sub 0.53/Ga/sub 0.47/As/InP p-i-n/FET front-end optical receiver

In this paper a new technique to design monolithic integrated In/sub 0.53/Ga/sub 0.47/As/InP front-end optical receiver is presented. The proposed method, based on the minimization of the noise sources in the receiver through research into the best geometrical parameters, allows us to design the preamplifier directly coupled to the photodiode without any matching network. With a BER equal to 10/sup -9/ and a bit rate equal to 622 Mb/s, a front-end optical receiver sensitivity of -41 dBm was obtained.
