PURPOSE:To constitute an optical self-routing circuit by a simple constitution by operating a routing by using an optical gate which allows an optical signal to pass or reflects it only when the optical signal and an electric pulse signal are simultaneously impressed. CONSTITUTION:Optical packet signals A and B inputted to optical waveguides 101 and 102 are respectively branched into two by light branching equipments 103 and 104, and respectively made incident to optical gates 105, 106, 107 and 108. The output optical signals of the optical gates 106 and 108 are multiplexed by an optical multiplexer 109, the output optical signals of the optical gates 106 and 108 are multiplexed by an optical multiplexer 110, and respectively emitted from optical waveguides 111 and 112. An electric pulse generating circuit 113 impresses and supplies the same electric pulses to the optical gates 105 and 107, and the different electric pulses to the optical gates 106 and 108, and the optical gates 105-108 allow the optical signals to pass only when the optical signals and the electric pulse signals are simultaneously impressed. Thus, the optical self-routing circuit can be obtained by the simple constitution. |
