The transmission of 80-ps pulses through an 8 × 8 integrated optical crossbar switch is reported. The switching speed of the directional coupler switching element is measured at 1.33 GHz. This rise time can be improved with lower-capacitance interconnection techniques. Radio-frequency crosstalk due to acoustooptic coupling is measured at -12.3 dB at 1 GHz. The switching speed and modulation depth of the switch are acceptable for use in fast photonic switching networks. The demonstration of 100-Mb/s optical self-routing of 12.5-Gb/s information shows promise for an ultrahigh-speed packet or bit switching system.
