摘要： This disclosure is related to devices, systems, and techniques for determining an acceleration. For example, an accelerometer system includes a resonator and a light-emitting device configured to generate, based on an error signal, an optical signal. Additionally, the accelerometer includes a modulator configured to receive the optical signal, generate a modulated optical signal responsive to receiving the optical signal, and output the modulated optical signal to the resonator. A photoreceiver receives a passed optical signal from the resonator, where the passed optical signal indicates a resonance frequency of the resonator. Additionally, the photoreceiver receives a reflected optical signal from the resonator. The photoreceiver generates one or more electrical signals based on the passed optical signal and the reflected optical signal. Processing circuitry generates the error signal and determines the acceleration based on the one or more electrical signals.

摘要： This disclosure is related to devices, systems, and techniques for inducing mechanical vibration in one or more mechanical structures. For example, a system includes a mechanical structure extending along a longitudinal axis. The mechanical structure includes a set of mechanical beams, where the set of mechanical beams are configured to guide a modulated optical signal, and where the set of mechanical beams includes a first mechanical beam and a second mechanical beam separated by a gap. The first mechanical beam includes at least one of a first corrugated inner edge parallel to the longitudinal axis and a first corrugated outer edge parallel to the longitudinal axis. The second mechanical beam includes at least one of a second corrugated inner edge parallel to the longitudinal axis and a second corrugated outer edge parallel to the longitudinal axis.

摘要： This disclosure is related to devices, systems, and techniques for securing one or more mechanical structures to a frame of a proof mass assembly. For example, a system includes a light-emitting device configured to emit an optical signal, a circuit including a modulating device configured to modulate the optical signal to produce a modulated optical signal, and a mechanical assembly. The mechanical assembly includes an anchor structure including a set of connecting structures configured to pass the modulated optical signal, where the set of connecting structures includes two or more connecting structures, and where a width of each connecting structure of the set of connecting structures is less than a maximum width of the anchor structure and a mechanical structure intersecting with the anchor structure, the mechanical structure configured to guide the modulated optical signal.

摘要： An optomechanical device optomechanical device for stabilizing an optomechanical resonator comprising a circuit configured to generate a first optical signal and a second optical signal, modulate the first optical signal, modulate the second optical signal, and combine the first optical signal and the second optical signal into a combined optical signal to direct the combined optical signal into an assembly. An inner sidewall of a first beam structure of the assembly has a first inner spatial frequency correspond to a second inner spatial frequency of an inner sidewall of a second beam structure of the assembly and an outer sidewall of the first beam structure has a first outer spatial frequency correspond to a second outer spatial frequency of an outer sidewall of the second beam structure.

摘要： A method may comprise: generating an optical frequency comb; applying a filter in a first configuration to the generated optical frequency comb to select a first frequency of the optical frequency comb, wherein, in the first configuration, the first frequency aligns with a first pass-band of the filter, and a second frequency of the optical frequency comb does not align with a second pass-band of the filter; altering the filter to a second configuration to shift the first pass-band and the second pass-band to a shifted first pass-band and a shifted second pass-band; and applying the altered filter to the generated optical frequency comb to select the second frequency of the optical frequency comb, wherein the second frequency aligns with the shifted second pass-band of the filter, and the first frequency of the optical frequency comb does not align with the shifted first pass-band of the filter.
