We demonstrate a compact, thermally reconfigurable reflection suppressor on a silicon-on-insulator (SOI) platform, without reliance on nonreciprocal mechanisms. A reflection suppression ratio of 40 dB is achieved with a footprint of 105 μm in length. The insertion loss of the device is below 0.15 dB, and its total power consumption stays below 20 mW. The operation bandwidth depends on the frequency dependence of the back reflection going into the suppressor, which is predominantly determined by the distance between the device and the source of reflection. In this work, a 20 dB reflection suppression bandwidth of 20.7 GHz was achieved.
