Abstract :
A dual-drive Ti:LiNbO/sub 3/ Mach-Zehnder modulator is used as an optoelectronic exclusive-OR gate. The logic capability is employed for simultaneously multiplexing and encoding two electrical 5-Gb/s signals on an optical beam. Demultiplexing schemes for differentially encoded signals involving optical or electrical time demultiplexing are presented. The dual-drive modulator offers a simple and relatively inexpensive way of encoding a 10-Gb/s pseudorandom bit string using one 5-Gb/s pattern generator.<>
