我们实验证明了一个4×4的无阻塞硅热光（TO）开关结构组成的三级可调谐广义马赫-曾德尔干涉仪。所有24个路由状态的非阻塞交换的特点。该器件的封装尺寸为4.6 mm×1.0 mm。测量显示，所有开关状态的最差串扰为−7.2 dB。片上插入损耗在3.7-13.1 dB的范围内。平均TO开关功耗为104.8 mW。
We experimentally demonstrate a 4×4 nonblocking silicon thermo-optic (TO) switch fabric consisting of three stages of tunable generalized Mach–Zehnder interferometers. All 24 routing states for nonblocking switching are characterized. The device’s footprint is 4.6 mm×1.0 mm. Measurements show that the worst cross talk of all switching states is −7.2 dB. The on-chip insertion loss is in the range of 3.7–13.1 dB. The average TO switching power consumption is 104.8 mW.
