光交换技术的发展趋势

The Developing Trend of Optical Switching Technology

本文根据国内外近十年来发表的光交换器件及光交换系统方面的文献对光交换技术的发展趋势加以综述。本文把光交换器件分为两大类,即光相关器件与光逻辑器件,并举例加以说明。对光交换系统则分为空分交换,时分交换及波分交换三大类予以叙述。并指出三维交换矩阵的开发可能是光交换技术独立于电子交换技术的一种新模式,利用光传输在时空上的特点,估计在近几年内光交换技术还会有新的突破。

A summary on developing trend concerning the technique ofoptical switching is got from the optical switching components and opticalswitching systems, which were published during the past decade. Opticalswitching component. are described according to two categories, they areoptical relative device and optical logic device, and are examplifiedrespectively. Optical switching systems are illustrated as three kinds ofsystem, those are space division switching, time division switching andwave division switching. The author points out that the development of3-dimension switching array may be a new mode of optical switchingtechnique which will be independent from the electronical switchingtechique. Using the merits of optical transmission in time and space, it isexpected that the optical switching technique will be developed rapidlyin recent years.
