光时分复用 (OTDM) 将众所周知的电时分复用技术延伸并扩展到光领域。在OTDM中，光数据流是通过时分复用多个较低比特率光流来构造的。通过消除电子设备有限带宽所带来的限制并利用光学设备固有的高速特性，可以创造超高速传输和交换的机会。概述了光时分复用和解复用方面的最新工作。描述了影响系统架构的设计考虑因素。强调限制系统性能的因素，例如复用通道之间的串扰。介绍了使用锁模半导体激光器和高速 Ti:LiNbO/sub 3/波导开关/调制器的短脉冲进行极高比特率光学时分复用系统实验的示例。<>
Optical time-division multiplexing (OTDM) extends and expands the well-known techniques of electrical time-division multiplexing into the optical domain. In OTDM, optical data streams are constructed by time-multiplexing a number of lower-bit-rate optical streams. Opportunities for very high-speed transmission and switching are created by removing limitations set by the restricted bandwidth of electronics and by capitalizing on the inherent high-speed characteristics of optical devices. An overview of recent work in optical time-division multiplexing and demultiplexing is presented. Design considerations affecting system architecture are described. Emphasis on the factors that limit system performance, such as crosstalk between multiplexed channels. Examples of very high bit-rate optical time-division multiplexed system experiments using short pulses from mode-locked semiconductor lasers and high-speed Ti:LiNbO/sub 3/ waveguide switch/modulators are presented.<>
