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。
This article reviews the development trend of optical switching technology according to the literature on optical switching devices and optical switching systems published at home and abroad over the past decade. In this paper, the optical switching devices are divided into two categories, namely light-related devices and optical logic devices, and to illustrate an example. The optical switching system is divided into air space switching, time switching and wavelength switching to be described in three categories. It is pointed out that the development of 3D exchange matrix may be a new model that optical switching technology is independent of electronic switching technology. Utilizing the characteristics of optical transmission in time and space, it is estimated that there will be a new breakthrough in optical switching technology in recent years.
