借助波导转角镜结构,利用古斯-汉欣空间位移和热光效应折射率调制的有效组合,提出了波导反射模式数字式热光开关结构。在给定入射角的条件下优化了空间古斯-汉欣位移,在具有古斯-汉欣效应的本征态下,反射光束出现了较大的跳跃。在1.0 μm 厚硅膜的绝缘体上硅平台上,单模输入波导和多模干涉波导结构之间的导模本征态匹配,验证了1×3数字式光开关功能。实验中,器件结构引起的光损耗为0.3 dB,开关功率为130~150 mW,开关时间约为50 μs,相邻输出端之间隔离度为15 dB。与马赫-曾德尔干涉仪型的2×2热光开关和等离子体效应热光开关的最新结果进行比较证明了该数字式热光开关的先进性。

A free-space 1\times2 wavelength-selective switch (WSS) based on thin-film filter technology is proposed. The 1\times2 WSS is fabricated with an electromagnetic actuator, a reflecton prism, a narrow-band thin-film filter, and three fiber collimators. The working principle and the configuration of WSS are illuminated. The experimental results indicate a fiber-to-fiber insertion loss ranging from 1.109 to 1.249 dB with 2-V voltage input, which satisfies the application of optical fiber communication.
