摘要:

近年来,随着云计算、数据中心的迅速发展,光互连凭借其在功耗、速度和带宽等方面具有电互连无可比拟的诸多优势,获得越来越多的关注。为了充分发挥光互连带宽优势,发展波分复用(WDM)、偏振复用(PDM)以及模式复用(MDM)等技术是一种有效途径。而将多种复用方式综合运用则可形成一种多维混合复用技术,从而显著提升光互连通道数量和传输容量。鉴于片上集成(解)复用器是实现多通道并行传输复用系统的关键器件,着重介绍总结了基于硅光子技术实现的超小型片上集成(解)复用器件的进展,包括WDM、PDM、MDM复用—解复用器件以及混合复用—解复用器件。

Abstract:

As the demands of the data communications increase quickly for the applications of cloud-computing as well as data centers,optical interconnects have been very attractive because of the unique advantages on the aspects of low power consumption,high speed and large bandwidth.It is effective to enhance the link capacity by utilizing multiplexing technologies like wavelength-division-multiplexing(WDM),polarization-division-multiplexing(PDM),as well as mode-division-multiplexing(MDM).It will become very useful when these multiplexing technologies are combined to work together as a hybrid multiplexing technology.Definitely the multiplexer is one of the most important devices for a multiplexed optical interconnect link.A review for the recent progress of ultracompact on-chip multiplexers was given,including WDM devices,PDM devices,MDM devices,and hybrid multiplexers.

Key words: silicon photonic nanowire, wavelength division multiplexing, polarization division multiplexing, mode division multiplexing
