Abstract :
Receiver optoelectronic integrated circuits (OEICs) in which AlInAs/GaInAs HEMTs and GaInAs pin PDs were integrated monolithically on InP substrates were studied. Good uniformity of device characteristics over a 2-inch whole wafer was obtained. Three different types of receiver circuits, i.e high impedance type, trans-impedance type, and straightforward termination type, were fabricated and are discussed. The sensitivity of -30.4 dBm was obtained for 1.2 Gbit/s NRZ signals from the high-impedance type OEIC, into which an equaliser was also integrated. These performances are good enough for practical use in optical communication systems operating at giga-bit/s data rates
