Paper Abstract

This paper report describes the results of the development of a multi-channel Optical Fiber Crossbar Switch (OFCS). The switch operates in the optical domain using GaAs semiconductor lasers to transmit wideband multiple channel optical data over fiber optic cables. A 16 X 16 crossbar OFCS switching system was developed suing GaAs optoelectronic integrated circuit receivers (OEICs) and GaAs integrated laser driver circuits output to GaAs lasers operating at 830 nm. Essentially error free performance has been obtained at a data bandwidth of 410 MBPS. The OFCS can be completely reconfigured in less than 50 nanoseconds under computer control. In addition, the system was designed with a 32 X 32 crossbar switching capability, so that by simply installing additional optical transmitters and receivers the system has the capability for 32 X 32 optical crossbar switching. The fully populated OFCS has the capability to handle 12.8 gigabits per second (GBPS) of data while switching this data over 32 channels without the loss of a single bit during switching. The integrated GaAs transmitter drivers and OEIC GaAs optical receivers with data bandwidths exceeding 2 GBPS.
