Abstract

A monolithic integration of InGaAs PIN photodiodes and InP junction field-effect transistors has been demonstrated. The photodiodes show a frequency response beyond 22GHz with a quiantum efficiency of 65%. The FETs have a transconductance of 35mS/mm, a leakage current of less than lOnA/mm and a gate capacitance of less than 0.7pF/mm. The cut-off frequency of the FETs is estimated to be 7GHz. The receiver sensitivity is calculated to be -33dBm at 2 GHz.
