Patent ID: 8867026

Claim:
A method of determining a gravitational force, the method comprising: providing at least one first radiation to at least one optomechanical oscillator, the at least one optomechanical oscillator being structured to deform under the gravitational force to cause a shift in resonance associated with the at least one optomechanical oscillator, wherein the at least one optomechanical oscillator includes a photonic crystal separated into a first portion and a second portion by an air slot, a width of the air slot is structured to be altered under the gravitational force; receiving at least one second radiation from the at least one optomechanical oscillator, wherein the at least one second radiation is associated with the shift in the resonance, wherein the air slot forms a waveguide through which the first radiation and the second radiation travel; and determining the shift in the resonance based on the first and second radiations, wherein the shift in the resonance is associated with the alteration of the width of the air slot through which the first and second radiations travel.
