:我们报告了一种使用硅光子技术的波长选择开关(WSS)的新颖设计。它由 1 × 4 交织器、连接到折返波导的阵列波导光栅 (AWG) 和 1 × 2 光学马赫-曾德尔干涉仪开关组成。在所提出的 WSS 中,折返波导使 AWG 能够用于解复用和复用。因此,WSS 的波导交叉点比传统配置少。此外,采用 CMOS 技术在 5 mm × 10 mm SOI 芯片上制造了 20 通道、200 GHz 间距、1 × 2 折返型 WSS。
: We report on a novel design of a wavelength selective switch (WSS) using silicon photonics technology. It comprises of 1 × 4 interleavers, arrayed-waveguide gratings (AWGs) connected to fold-back waveguides, and 1 × 2 optical Mach-Zehnder interferometer switches. In the proposed WSS, fold-back waveguides enable the AWGs to be used for both demultiplexing and multiplexing. Therefore the WSS has less waveguide crossings than a conventional con fi guration. Moreover, a 20-channel, 200-GHz spacing, 1 × 2 fold-back type WSS was fabricated on 5 mm × 10 mm SOI chip using CMOS technology.
