中文摘要： 基于无栅格波长选择光开关（WSS）带宽可变光交换技术是下一代灵活、透明、智能化全光网络的关键技术之一。随着全光网络组网方式的复杂化，无栅格WSS的需求量也将大幅度增长，同时也带来了成本、功耗以及尺寸等方面问题。因此，本项目拟从未来平面集成的发展角度，着重对陡峭平坦通带、低损耗、低功耗及可扩展的硅基集成无栅格WSS特性及实现进行研究，并利用0.18 μm成熟的兼容CMOS工艺对16通道且最小通道间隔为50GHz的硅基集成无栅格1×4 WSS进行验证分析。具体内容包括：建立由基于interleaver级联1×M/2微环滤波器阵列模块、可变衰减器级联硅基波导相位调制器模块以及可重构的M×N微环阵列模块级联而成硅基集成无栅格WSS可扩展架构；研究分析该架构下无栅格WSS传输特性；采用垂直耦合系统验证无栅格1×4 WSS。本项目所形成的研究成果可为我国掌握下一代网络关键技术提供科学数据支持。

英文摘要： Due to the rapid development of Internet and the Internet of Things as well as the population of the data services, the traditional optical network based on fixed grid technology is being challenged. As a result, the next generation optical network evolutes towards to a flexible，transparent and intelligent one. As a key component for realizing the elastic optical network, the gridless wavelength selective switch (WSS) is able to multiplex and switch variable spectral bands. However, with the rising complexity of the networking model, the number of the gridless WSS will be significantly increased, bringing the issues of cost, power consumption, and the size. To solve these issues, this project will propose a monolithic gridless WSS based on photonic integrated circuit, which is consisted of a 1×M/2 microring resonant wavelength demultiplexer assistant with interleaver, variable optical attenuator (VOA) array, phase modulator (PM) array, and a reconfigurable M×N cross-grid array of microring resonant wavelength multiplexer,then focus on the study of this gridless wavelength selective switch on SOI and demonstrate the design for a gridless 1×4 WSS by a 0.18 μm standard commercial CMOS line.The 1×4 WSS has 16 channels and the minimum channel spacing of 200 GHz. The device will find its application in the elastic op
