  • Patent number: 11815718
    Abstract: Techniques relating to an improved optical waveguide are described. The optical waveguide includes an upper and lower waveguide that each comprise a first and second layer, in which photons are transferred from the lower waveguide to the upper waveguide. A structured subwavelength coupling region is included, for example, in the first upper waveguide layer. The fill factor of the subwavelength grating coupling region is increased in the direction of light propagation to increase the index of refraction of the structured subwavelength coupling region and therefore improve photon transfer from the lower waveguide. Additionally, the width of the optical waveguide (at least along the structured subwavelength coupling region) remains constant as the fill factor increases.

  • Patent number: 11586094
    Abstract: Improved architectures and related methods for enhancing entangled photon generation in optical systems are described. Photons from a light source are coupled from the fundamental mode into an optical resonator in a higher-order mode. The optical resonator comprises a photon generation portion configured to generate entangled photons from the coupled photons. The entangled photons are selectively extracted from the optical resonator in the fundamental mode while the remaining photons propagate through the optical resonator mode and combine with the source photons entering the optical resonator. While the source photons propagating or entering the optical resonator resonate within the optical resonator, the entangled photons are not resonant with the optical resonator, and are selectively extracted before traversing a complete cycle in the optical resonator. Extracted entangled photons can then be output for use in, for example, a communication system.

  • Patent number: 11536908
    Abstract: A multilayer waveguide coupler comprising a first grating and a second grating is provided. Each first copropagating waveguide of the first grating has a first periodically modulated width. Each second copropagating waveguide of the second grating has a second periodically modulated width. The second grating is positioned so that a phase offset is present between the first periodically modulated width of the first copropagating waveguides and the second periodically modulated width of the second copropagating waveguides. The grating spaced distance and phase offset are selected so that light diffracted out of the first copropagating waveguides and the second copropagating waveguides in the first direction interferes constructively to form the first light beam and light diffracted out of the first copropagating waveguides and the second copropagating waveguides in the second direction interferes destructively.

  • Patent number: 11486706
    Abstract: A method for reducing or eliminating bias instability in a SBS laser gyroscope comprises introducing a first pump signal propagating in a CW direction, and a second pump signal propagating in a CCW direction in a resonator; generating a CCW first-order SBS signal and a CW first-order SBS signal in the resonator; increasing a power level of the first pump signal above a threshold level such that the CW first-order SBS signal generates a CCW second-order SBS signal; and increasing a power level of the second pump signal above the threshold level such that the CCW first-order SBS signal generates a CW second-order SBS signal. Above the threshold level, an intensity fluctuation of the first-order SBS signals disappear and their DC power are clamped at substantially the same power level. A Kerr effect bias instability of the SBS laser gyroscope is reduced or eliminated by the clamped first-order SBS signals.
