Paper Abstract

We report on the first monolithic integrated transimpedance photoreceiver operating at 0.85 µm wavelength using GaAlAs-GaAs heterojunction phototransistor (HPT) and heterojunction bipolar transistors (HBT). The design and the fabrication process are presented, taking into account the specific characteristics of high current gain-high speed HPT and HBT. Using 26 kΩ external feedback resistor the monolithic photoreceiver has a bandwidth of 80 MHz with a transimpedance gain of 7000 V/A and a sensitivity of -30 dBm. These preliminary results are very closed to the theoretical performances predicted for this circuit capable to operate for local network optical links at 140 Mbits with a sensitivity of -40 dBm.
