Abstract
A method detects an acceleration. The method includes providing a spatial mode filter positioned such that light emitted from the spatial mode filter is reflected by at least a portion of a reflective surface. The spatial mode filter and the portion of the reflective surface form an optical resonator having an optical resonance with a resonance lineshape. The method further includes emitting light from the spatial mode filter and irradiating the portion of the reflective surface. The portion of the reflective surface is responsive to acceleration of the optical resonator by changing curvature. The method further includes measuring a change of the resonance lineshape due to the acceleration of the optical resonator.
