Abstract: An optomechanical gravimeter includes: a first and second accelerometer; and a spacer member interposed between the first accelerometer and the second accelerometer such that the first accelerometer and the second accelerometer independently include: a basal member; a test mass disposed on the basal member; a flexural member interposed between the basal member and the test mass such that the test mass is moveably disposed on the basal member via flexing of the flexural member; an armature disposed on the basal member and opposing the test mass and the flexural member such that: the armature is spaced apart from the test mass; a cavity including: a first mirror disposed on the test mass; a second mirror disposed on the armature, the spacer member providing a substantially constant distance of separation between a first measurement point of the first accelerometer and a second measurement point of the second accelerometer.

Abstract: An optomechanical reference includes a basal member; a flexure that includes: a floating link; a first flexural member; and a second flexural member such that: the floating link is moveably disposed; a first stator; a second stator; a first cavity including: a first primary mirror; a first secondary mirror; a first optical coupler in optical communication with the first secondary mirror; and a first cavity length; and a second cavity including: a second primary mirror; a second secondary mirror; a second optical coupler; and a second cavity length.

Abstract: An optomechanical laser includes: a basal member; a mechanical transducer; a laser disposed on the mechanical transducer, the laser being displaced along the displacement axis in response to a displacement of the mechanical transducer relative to the basal member; a mirror disposed on the armature in optical communication with the laser and opposing the laser; the armature disposed on the basal member and rigidly connecting the mirror to the basal member such that the mirror and the armature move in synchrony with the basal member, and the armature provides a substantially constant distance between the basal member and the mirror; and a cavity comprising: the laser; the mirror; and a cavity length between the laser and the mirror that changes in response to displacement of the laser according to the displacement of the mechanical transducer relative to the basal member, the optomechanical laser providing laser light.
