ABSTRACT:
A high speed opto-electronic crossbar switch 10 disposed to selectively connect signals carried by first and second input optical beams to an output node 42. The inventive switch 10 includes a selectively actuatable photodetector network 22 for converting the signals carried by the first and second input beams to electrical output signals, and for impressing these output signals upon the output node 42. The photodetector network 22 has a first photodetector 30 in optical alignment with the first input beam, and a second photodetector 32 in optical alignment with the second input beam. The inventive crossbar switch 10 further includes a multiplexer 26 for actuating the first and second photodetectors 30, 32 in response to a control signal. The invention also includes a laser diode circuit 24 for illuminating the first and second photodetectors 30, 32 in response to the control signal.
