演示了一种紧凑型集成 1×2 波长选择开关 (WSS)，其结构设计使得 WSS 没有波导交叉。通过采用环回配置，WSS 中只需要一个阵列波导光栅。通道间隔为100 GHz，通道数为40。所选波长的测量传输损耗<； 8.1dB，两个输出端口的平均串扰分别为23.0和40.7dB。
A compact integrated 1×2 wavelength-selective switch (WSS) is demonstrated for which the structure is designed such that the WSS has no waveguide crossings. By employing a loopback configuration, only one arrayed-waveguide grating is needed in the WSS. The channel spacing is 100 GHz and the number of channels is 40. The measured transmission loss of the selected wavelength was <; 8.1dB, and the average crosstalk from two output ports were 23.0 and 40.7 dB.
