Abstract :
A high-isolation (60 dB) 10×10 optoelectronic switch matrix with surface-depleted photoconductive crosspoints is reported. The device is designed for a bandwidth greater than 1 GHz and an isolation level greater than 60 dB. Ten 1.8-GHz channels are supported with 0-dB insertion loss and >125 dB/Hz dynamic range. The novel crosspoints require reliability improvement because they are unstable
