Paper Abstract

A novel ultrasensitive integrated nanomechanical optical sensor is proposed and analyzed. The photonic device consists of a silicon nitride disk resonator formed by a horizontal slot-waveguide acting as a circular cantilever. The device sensitivity results from the product of the sensitivities of the slot-waveguide and the disk resonator. A deflection sensitivity of 11.5 nm-1 is predicted, representing an enhancement of 4 orders of magnitude as compared to state-of-the-art microcantilever sensors.
