使用硅光子线波导，我们构建了紧凑的1 × 1，1 × 2和1 × 4马赫-曾德尔干涉仪型光开关上的硅绝缘体衬底上，并通过热光效应演示了他们的开关操作。这些开关分别小于140 × 65、85 × 30和190 × 75 μ m。在1550 nm波长处，我们获得了大于30 dB的消光比，开关功率低至90 mW，开关响应时间小于100 μ s。此外，还成功演示了1x 4交换机的交换操作。(c)2005年，美国光学学会。
Using silicon photonic wire waveguides, we constructed compact 1 x 1, 1 x 2, and 1 x 4 Mach-Zehnder interferometer type optical switches on a silicon-on-insulator substrate and demonstrated their switching operations through the thermo-optic effect. These switches were smaller than 140 x 65, 85 x 30, and 190 x 75 mu m, respectively. At a 1550-nm wavelength, we obtained an extinction ratio larger than 30 dB, a switching power as low as 90 mW, and a switching response time of less than 100 mu s. Furthermore, switching operations were successfully demonstrated for the 1 x 4 switch. (c) 2005 Optical Society of America.
