摘　　要：随着硅光子技术的发展,硅光子集成器件在信号处理上的也应用越来越广泛。在物理层面上的光信号处理包括五类,分别对应时间、振幅相位、偏振、波长、空间五个维度,对应的技术分别是时分复用、高阶调制格式、光的偏振复用、波分复用以及空分复用(包含模分复用)。我们的研究主要集中在波长、偏振、模式三个维度上来进行硅基的片上光信号处理。介绍了三类用于波长、偏振和模式信号处理的硅光子器件。第一类是波长维度上的,包括片上光学梳状滤波器和交织型滤波器;第二类包括偏振分束器和偏振旋转器;第三类包括一个特殊设计的超紧凑纳米束光开关,两个大规模的模式和偏振选择性光开关。这些器件为片上的光学信号处理提供了更多的选择,在实际应用中也有很大的潜力。With the development of silicon photonic technology,silicon photonicintegrated devices have been widely used in optical signal processing.In physical dimensions,an optical signal can be varied in five dimensions including time,amplitude and phase,polarization,wavelength and space.The corresponding multiplexing technologies are time division multiplexing(TDM),high-order modulation formats,polarization division multiplexing(PDM),wavelength division multiplexing(WDM)and space division multiplexing(SDM),respectively.In our research,we focus on three dimensions including wavelength,polarization and mode to process optical signal.In this paper,we present three types of silicon photonic devices for optical signal processing.We experimentally demonstrate optical filtering,polarization splitting and rotating,and mode(de)multiplexing and switching in silicon devices.These silicon photonic devices provide more freedom for on-chip optical signal processing,and have a great potential in practical applications.
