Abstract
By employing a hybrid technology using electronic and optical integration, optical isolation levels can be attained in a switch matrix without the need to switch light. Bandwidths in several GHz, subnanosecond switching time and crosstalk below 50 dB have been demonstrated in monolithically integrated optoelectronic switch matrices. These devices show high promise as central switches in star configuration communication systems where very high bandwidth or very large array size is required. Advantages over foreseeable alternative technologies include size and power consumption as well as performance. In addition, optoelectronic switch matrices have unique properties that suggest their application in a number of signal processing situations where precise broadband signal delays are required, such as in the phasing of arrays, or the production of tunable filters. Recent work in these areas will be described.
