 Snap-Release Optomechanics

A new optomechanical system is designed and fabricated from a single layer of 400 nm thick LPCVD Si3N4. This new system utilizes the high stress of LPCVD Si3N4 to realize a nanomechanical resonator to within 100 nm of an optical ring resonator fabricated from the same layer of LPCVD Si3N4. Initial results of the characterization of such devices are presented, as well as a demonstration of optomechanical coupling through the optical spring effect. This design can be integrated into photonic circuits through optical waveguide, and shows promise for a number of immediate applications, including layer characterization and use in sensors.
