摘要
波分复用/解复用器作为数据传输的核心器件,广泛应用于片上光互联网络中,其中最重要的指标就是器件的尺寸,插入损耗和串扰大小,为解决传统硅基阵列波导光栅尺寸较大,阵列波导光栅光强不均的问题,我们提出了 一种基于绝缘体上硅(SOI)的环形反射器辅助多模干涉波导的四通道波分复用器,可以实现不同通道的波长分离.其核心尺寸仅为10 μm× 34 µm,最小相邻通道串扰为-14.42 dB.
Abstract
As a core component for data transmission,the wavelength division multiplexer/demultiplexer(WDM)is extensively utilized in on-chip optical interconnect networks,where the most crucial parameters for these devices in-clude device size,insertion loss,and crosstalk levels.To address the issues of large size and uneven optical power dis-tribution in conventional silicon-based arrayed waveguide gratings(AWGs),a 1×4 WDM based on a silicon-on-insu-lator(SOI)platform incorporating a ring reflector-assisted multimode interference waveguide is proposed,which can realize the wavelength separation of different channels.The core size of the device is only 10 μm × 34 μm,and the minimum crosstalk between adjacent channels is-14.42 dB.
