Detailed measurements of crosstalk under multichannel operation of several eight-channel p-i-n/HBT monolithic array photoreceiver modules are reported. At an operating speed of 2.5 Gb/s, with an average sensitivity of -25 dBm, crosstalk penalties ranging from 0.2 dB to 2.6 dB for a bit-error rate of 10/sup -9/ have been measured for adjacent channels receiving -22 dBm to -12 dBm of optical signal power. This is the first report of the crosstalk performance of a fully packaged OEIC array photoreceiver module.
