ABSTRACT:
An optical switch circuit is configured as a matrix array to arbitrarily switch the connections between optical transmission channels. The optical switch circit comprises a plurality of optical splitter coupled to input transmission channels, a plurality of optical switches arranged on the matrix crosspoints, each switch comprising an optoelectronic element and a light modulating element functioning as an electrooptic element, and a plurality of optical combiners coupled to output transmission channels. Thus, a small-sized optical switch circuit suitable for integration is realized. With this circuit, small crosstalk and high speed switching without distortion of broadband signals are expected. Further, this circuit provides a wide adaptability such that light transmitted through multi-mode optical fiber can be switched.
