摘要

现代光纤通信网络使用波分复用技术极大地提升了网络传输容量。基于硅基液晶技术的波长选择开关使光纤网络运营商在网络节点处可以灵活地调度各个波长信道，让光纤通信网络在波长级具有可重构性，大幅降低了网络的传输和运营成本。因此，波长选择开关已经成为现代光纤通信网络的核心组件。本文回顾了波长选择开关的发展历程，重点介绍了其在光纤通信网络中扮演的角色，阐述了硅基液晶器件各项特性对波长选择开关关键技术指标的影响和改进方法。本文从器件、系统和网络等方面对硅基液晶技术在通信系统中的应用进行了系统的综述，旨在让广大读者对硅基液晶器件和可重构光纤通信网络有比较全面的了解，并从一定程度上对该领域的研究发展有所促进。

Abstract

Modern telecommunication networks use wavelength division multiplexing (WDM) technology to increase the transmission capacity of the fibres. Wavelength selective switches (WSSs) based on the liquid crystal on silicon (LCOS) technology enable network operators to route the signals on the wavelength basis

which significantly reduce the operational expenses (OpEx). This paper reviews the development of LCOS-based WSSs and its role in reconfigurable all-optical telecommunication networks. The key performance parameters for the WSSs and LCOS devices are explained in great details

with an aim to promote the research and development of this field.
