摘要

波长解复用是集成光学中一个特别重要的功能，可以用光子晶体来实现。目的是准确地提取数据流中的波长。在这项工作中，我们研究了一种基于介电棒构成的二维光子晶体的波长解复用新拓扑。所研究的解复用器是基于优化参数的光滤波器，以提取通信窗口对应频率附近的四个不同波长。结果表明，该解复用器结构通道间的串扰在-19.19 ~ -44.1 dB范围内，通道间距为0.96 nm。利用时域有限差分法对本文给出的仿真结果进行了验证和分析。

Four channel optical demultiplexer based on L2 photonic crystal microcavity

The wavelength demultiplexing is a particularly important function in integrated optics and can be realized using photonic crystals. The aim is to extract accurately the wavelengths in a data flux. In this work, we investigate a new topologies of wavelength demultiplexing based on two-dimensional photonic crystals constituted of dielectric rods spread in a square network. The studied demultiplexer is based on optical filters with optimized parameters in order to extract four different wavelengths in the vicinity of frequencies corresponding to communication windows. It was found that the crosstalk between the structure channels of the demultiplexer are in the range of –19.19 and –44.1 dB and the channel spacing is equal to 0.96 nm. The simulation results presented in this paper are performed and analyzed using the FDTD method.
