High sensitivity, high gain, long wavelength OEIC receiver with monolithically integrated three-stage preamplifier

A GaAs-on-InP long wavelength OEIC receiver, with a monolithically integrated three-stage preamplifier, was designed using SPICE and fabricated. The three-stage OEIC receiver exhibited excellent performances, such as −32.5 dBm receiver sensitivity and 85 dBΩ transimpedance at 600 Mbit/s. These results indicate the feasibility of integrating large scale electronic circuits, which are considered as the OEIC merits, caused by using both GaAs-on-InP heterostructures and SPICE.
