Abstract

We demonstrate a low-crosstalk 2 x 2 thermo-optic switch with silicon wire waveguides. The device is based on a 2 x 2 array of Mach-Zehnder interferometer (MZI) switches. Lowest crosstalk levels of -50 dB and -30 dB are obtained for 'bar' and 'cross' switching states, respectively. An intersection in the switch is important for low-crosstalk operation. The power consumption of one MZI element switch is 40 mW and the total power consumption of the device is at most 160 mW.

摘要

我们展示了一种采用硅线波导的低串扰2×2热光开关。该器件基于一个2×2马赫-曾德尔干涉仪（MZI）开关阵列。在“条形”和“交叉”开关状态下，分别获得了低至-50 dB和-30 dB的串扰水平。开关中的交叉点对于低串扰操作很重要。一个MZI元件开关的功耗为40 mW，该器件的总功耗至多为160 mW。
