Abstract: In some examples, a micro-electro-mechanical system (MEMS) optical accelerometer includes a housing comprising an internal chamber that includes a Fabry-Perot cavity and a proof mass affixed to the housing via one or more elastic elements, a light source configured to emit radiation, a first detector configured to receive radiation transmitted through the Fabry-Perot cavity and configured to generate one or more signals that indicate a position of the proof mass. The MEMS optical accelerometer further comprises an atomic wavelength reference and a second detector configured to detect radiation transmitted through the atomic wavelength reference and configured to generate one or more signals that indicate a wavelength of the radiation emitted by the light source, and a servomechanism electrically coupled to the second photo detector and the light source, configured to adjust the light source to maintain the radiation emitted by the light source at approximately a selected wavelength.

Abstract: An optical frequency comb generation system includes an optical waveguide portion having a uniform width, a first chirped Bragg grating disposed at one end of the optical waveguide portion and a second chirped Bragg grating disposed at the other end of the optical waveguide portion. The first chirped Bragg grating includes at least a first periodic variation having a first refractive index and a second periodic variation having a second refractive index. The second chirped Bragg grating includes the at least first and second periodic variations. A first cavity associated with a first resonant frequency extends between the first periodic variation of the first chirped Bragg grating and the first periodic variation of the second chirped Bragg grating. A second cavity associated with a second resonant frequency extends between the second periodic variation of the first chirped Bragg grating and the second periodic variation of the second chirped Bragg grating.

Abstract: 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.
