Title: Resonator for force detection
Authors: Somekh, M 
Issue Date: 25-Aug-2020
Abstract: Provided herein is a resonator for force detection. The resonator comprises a stack of: a cavity containing a cavity medium having a first refractive index; a first diffraction grating having a grating period; and a first covering medium having a second refractive index. Once a resonating condition is satisfied, the cavity allows a plurality of propagating modes for the beam in the cavity and only one propagating mode for the beam outside the cavity. The plurality of propagating modes in the cavity resonates to generate different resonance peaks corresponding different sensitivity levels. By working in different regimes, the resonator is able to provide high sensitivity and large dynamic range for force detection.
