Abstract

We propose a nanomechanical channel drop switch by controlling the submicron distance between a nanocavity and photonic crystal (PC) waveguide with an ultrasmall electrostatic comb actuator. Light propagating in the PC waveguide is coupled with a nanocavity and emitted as a drop signal under a resonant condition. The proposed switch has been fabricated by silicon micromachining. The drop efficiency has been controlled by 12.5 dB and gap change of 600 nm.
