摘　　要：波分复用技术已被证明可以有效提高近红外波段光通信的容量,并减小通道间串扰。然而,迄今为止,蓝绿光波段的波分复用系统仅支持有限数量的波长通道,通道间隔较大。这是因为没有适用于可见光的具有精细波长间隔的波分复用器和解复用器。为了阐述清楚这一问题,本文综述可见光波段波分复用技术的发展,特别关注基于集成光学相控阵解复用器的密集蓝绿波分复用技术的进展。最后,对目前蓝绿波分复用技术的发展趋势进行了总结和展望。Wavelength division multiplexing(WDM)technology has been shown to effectively increase the capacity of optical communications with minimal channel crosstalk in the near-infrared light band.However,to date,WDM systems in the bluegreen band support a limited number of wavelength channels with coarse channel spacing.This is because no multi/demultiplexers(MUX/DeMUX)exist that use fine wavelength spacing for visible light.To clarify this issue,this study reviews the development of WDM in the visible band and discusses the recent development of dense blue-green WDM based on integrated optical phased array DeMUX.Finally,the study summarizes and prospects the development trends of blue-green WDM.
