Paper Abstract

Repetitive pulse train of high peak power and very narrow pulse width from a mode-locked laser has been shown to be a viable candidate as a carrier wave for optical digital communication systems. In addition, the bit rate capacity of such a system can be increased many times by means of optical time-division multiplexing and demultiplexing. In this tutorial paper, a brief review of the optical multiplexing/demultiplexing scheme which utilizes ultrasonic standing wave Bragg cells (SUBC) is given. First, basic interaction mechanisms, working principle and modes of operation, major performance figures and design considerations, and terminal configurations for this acoustooptic scheme are described. Measured performance figures that have been obtained with some of the very high data rate multiplexers/demultiplexers using PbMo04 crystals are then discussed. This acoustooptic multiplexing/demultiplexing scheme should be highly useful for the implementation of multigigabits/sec optical space communication systems.
