Abstract: Systems and methods for a tunable radio frequency synthesizer utilizing optical frequency combs are provided. In one embodiment, an RF signal generator comprises: an SBS pump laser segment including a first and second SBS pump laser each generating SBS laser light at different respective frequencies; a TE/TM dual comb resonator comprising a comb optical resonator coupled to the first and second SBS pump lasers, wherein the comb optical resonator generates a pair of counter-propagating optical frequency combs of different polarities from the SBS laser light; a filter resonator segment configured to provide feedback to the TE/TM dual comb resonator to lock a relative position of the pair of counter-propagating optical frequency combs, the filter resonator comprising a tunable optical filter to output a discrete tuned RF signal output based on a comb line pair that includes a single comb line from each of the pair of counter-propagating optical frequency combs.

Abstract: Embodiments utilize an optical frequency comb generator coupled to an optical resonator of an optical gyroscope. The optical frequency comb generator generates an optical frequency comb having frequency peaks that each correspond to a respective resonance frequency of the optical resonator. A control servo can be coupled to the optical frequency comb generator and controls the optical frequency comb output from the optical frequency comb generator. In doing so, the optical frequency comb remains tuned to the resonance frequencies of the optical resonator during gyroscope operation.

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.

Abstract: A method for fiber-to-chip coupling is disclosed. The method comprises providing a photonic integrated circuit (PIC) that includes a substrate, a cladding layer on the substrate, and at least one waveguide embedded in the cladding layer, wherein the at least one waveguide has a waveguide interface. An optical fiber is positioned adjacent to the PIC, wherein the optical fiber has a fiber interface, and the fiber interface is aligned with the waveguide interface. A flowable inorganic oxide in liquid form is added to an area between the fiber interface and the waveguide interface. Thereafter, heat is applied to the area between the fiber interface and the waveguide interface for a period of time to cure the inorganic oxide, such that the optical fiber is coupled to the PIC. The cured inorganic oxide has a refractive index that substantially matches the refractive indices of the cladding layer and the optical fiber.

Abstract: A system for optical cooling comprises a substrate and a first waveguide supported by the substrate, with the first waveguide configured to provide optical cooling by fluorescence up-conversion. A first optical fiber is coupled to the first waveguide, with the first optical fiber configured to deliver cooling light to the first waveguide. A second waveguide is supported by the substrate, with the second waveguide adjacent to or coincident with the first waveguide. The interaction of the cooling light with the first waveguide produces a zone of local optical refrigeration based on the fluorescence up-conversion, such that the second waveguide is optically cooled by physical proximity to the first waveguide.
