本文描述了一种低成本、紧凑型(80 mm×50 mm)1×5波长选择开关的设计、建模、构造和测试。该开关的核心偏转元件是硅基向列相液晶空间光调制器。该交换机专为粗波分复用波长而设计，以便为接入网络中的客户端带来低成本、紧凑和强大的交换设计的优势。在系统开发阶段，利用三维打印技术设计了单个光机组件并制作了样机。实验结果表明，插入损耗为-13.8±1.4分贝，最坏情况下的串扰水平为-24.8分贝。对提高开关性能的途径进行了分析和讨论。
This paper describes the design, modeling, construction, and testing of a low-cost and compact (80 mm×50 mm) 1×5 wavelength-selective switch. The core beam-deflecting element of the switch is a nematic liquid crystal on silicon spatial light modulator. The switch is designed for coarse wavelength-division multiplexing wavelengths in order to bring the benefit of a low-cost, compact, and robust switching design toward the customer end in the access network. During the system development stage, a single optomechanical assembly was designed and prototyped using the three-dimensional printing technology. The experimental results show an insertion loss of -13.8±1.4 dB and a worst-case scenario crosstalk level of -24.8 dB. Approaches for enhancing the performance of the switch are analyzed and discussed.
