A signal-transparent switch matrix is presented which utilizes distributed optical interconnects and employs controlled conversion of optical signals into the electronic domain to achieve a very high quality broadband switching function. Optical — electronic conversions are inherent in photonic communication links; their use for switching imposes no new constraint if the quality of the signal path through the optoelectronic switch is sufficiently high [1, 2]. Optoelectronic switches can perform a similar function to all-optical switches in that the format of the signal is immaterial to the switch. Applications range from signal processing [3, 6, 8] to broadband switching matrices [4, 5] and high throughput ATM switches [7]. We present results obtained with a 10x10 switch constructed to demonstrate the broadband signal transparent switching capabilities of the optoelectronic matrix technology.
