ABSTRACT:
An opto-electric logic element comprises a semiconductor laser having a differential gain characteristic or an optical bistable characteristic and supplied with at least one light input, and a control circuit for varying an injection current supplied to the semiconductor laser in accordance with an input electrical signal. The logic element is capable of executing a logical operation between the optical signal and the electrical signal and can output the results of the logical operation as an optical signal.
