Abstract: A photonics device for threshold magnetometry includes an absorbent material with nonlinear optical susceptibility, such as a diamond material with nitrogen vacancy defects, that is disposed in an optical resonator. The optical resonator receives light from an input source and includes nonlinear optical properties that enable the resonator to undergo a nonlinear photon generation process at a certain threshold power level to generate photons at distinct frequencies from the input light. The absorbent material absorbs photons entering the resonator when excited, which causes the threshold power level to shift as a function of the absorption. This may cause the optical resonator to stop generating photons via the nonlinear photon generation process and output a change in power. The change in power can be used to determine the characteristics of a present magnetic field.

Abstract: A nonlinear wave mixing system with grating assisted phase matching is provided. The system includes a pump laser and a nonlinear waveguide. The pump laser is used to generate pump light at a select wavelength. The nonlinear waveguide is configured to generate produced light from the pump light that is directed into the nonlinear waveguide.

Abstract: An optical device comprises a waveguide core layer that includes a planar lens structure having a first end and a second end, with the planar lens structure including a plurality of lens tapers extending from at least one of the first or seconds ends in a convex-shaped array. The waveguide core layer also includes a waveguide slab that adjoins with the planar lens structure, such that the waveguide slab is in optical communication with the plurality of lens tapers. The plurality of lens tapers are configured to adiabatically transition an index of refraction from a first index value, external to the planar lens structure, to a second index value, internal to the planar lens structure.

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.

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.
