Abstract: An optical resonator device, which can be implemented in a Brillouin laser, comprises a first waveguide ring resonator having a first diameter, and one or more second waveguide ring resonators adjacent to the first waveguide ring resonator. The one or more second waveguide ring resonators each have a second diameter that is less than the first diameter. The one or more second waveguide ring resonators optically communicate with the first waveguide ring resonator, such that an optical signal in the first waveguide ring resonator optically couples into the one or more second waveguide ring resonators. The one or more second waveguide ring resonators is configured such that when the optical signal resonates within the first waveguide ring resonator and the one or more second waveguide ring resonators, the optical signal within the first waveguide ring resonator is suppressed.

Abstract: An integrated photonics chip for thermal imaging comprises a photonics substrate including a plurality of receiver elements. Each receiver element comprises a first grating coupler optically coupled to a first waveguide filter and configured to receive a first wavelength of light at a given angle, with the first waveguide filter configured to pass the first wavelength of light; and a second grating coupler optically coupled to a second waveguide filter and configured to receive a second wavelength of light at the given angle, with second waveguide filter configured to pass the second wavelength of light. Each receiver element receives the wavelengths of light from an object of interest that emits the light due to blackbody radiation, and receives the wavelengths of light at respectively different angles. Each grating coupler receives a unique wavelength of light with respect to the other wavelengths of light received by the other grating couplers.

Abstract: A stimulated Brillouin scattering gyroscope is provided. A pump laser generates continuous wave (CW) energy that travels through at least one bus waveguide to a waveguide resonator. A reflector is positioned within the waveguide resonator. The reflector is configured to pass at least some of the CW energy in a first direction and reflect at least some stimulated Brillouin scattering (SBS) energy in a second direction. A first detector is in operational communication with the at least one bus waveguide to detect CW energy. An output of the first detector used to at least adjust a pump laser frequency of the pump laser. A second detector is also in operational communication with the at least one bus waveguide. The second detector is used to determine phase shifts in detected SBS energy to determine at least rotation.

Abstract: An optical coupler comprises an adiabatic waveguide structure having a proximal end and a distal end, with the adiabatic waveguide structure comprising: a first waveguide comprising an input section at the proximal end; a first coupling section contiguous with the input section and extending toward the distal end; and a first laterally displaced section contiguous with the first coupling section. The first waveguide narrows along the first coupling section, from the input section to the first laterally displaced section. A second waveguide is separate from the first waveguide and comprises a second laterally displaced section adjacent to the proximal end; a second coupling section contiguous with the second laterally displaced section and extending toward the distal end; and an output section contiguous with the second coupling section. The second waveguide widens along the second coupling section, from the second laterally displaced section to the output section.

Abstract: Systems and methods for an integrated photonics vertical coupler are provided herein. In certain embodiments, a device includes a first waveguide having a first photon and a second photon propagating therein, wherein the first photon and the second photon are propagating in orthogonal modes. Further, the device includes a second waveguide having a second coupling portion in close proximity with a first coupling portion of the first waveguide, wherein a physical relationship between the first waveguide and the second waveguide along the length of the second coupling portion causes an adiabatic transfer of the first photon and the second photon into distinct orthogonal modes of the second waveguide at different locations in the second coupling portion.

Abstract: A bichromatic grating coupler comprises a two-dimensional diffraction grating structure, including a first sub-grating having a first periodic structure and a second sub-grating having a second periodic structure. The first and second sub-gratings are superimposed with respect to each other in the diffraction grating structure. A first optical port is coupled to the diffraction grating structure along a first direction, and a second optical port is coupled to the diffraction grating structure along a second direction. The first optical port is configured to direct a first light beam having a first wavelength to the diffraction grating structure, such that the first light beam is diffracted in a first direction by the first sub-grating. The second optical port is configured to direct a second light beam having a second wavelength to the diffraction grating structure, such that the second light beam is diffracted in a second direction by the second sub-grating.
