Abstract
An optomechanical device comprising an assembly, one or more laser devices configured to generate a first optical signal and a second optical signal, and circuitry. The circuitry is configured to modulate the second optical signal and output the first optical signal and the second optical signal to the assembly. A first element of a first beam structure shifts the first spatial frequency of the assembly by approximately 180 degrees and a second element of a second beam structure shifts the second spatial frequency of the assembly by approximately 180 degrees such that a first optical resonance is generated, which is probed by the first optical signal interacting with the assembly, and a second optical resonance is generated, which is probed by the second optical signal interacting with the assembly, where the first optical resonance and the second optical resonance are spectrally separated by a minimum threshold.
