Abstract

A bandwidth-tunable filter has been demonstrated based on a micro-electro-mechanical-system (MEMS) actuated single-crystalline silicon microtoroidal resonator. Bandwidth is tuned from 2.8 to 78.4 GHz by voltage control, the largest bandwidth tuning range reported to date to our knowledge in resonator-based filters. A 21.8 dB extinction ratio is attained as a dynamic add–drop filter.
