摘要： One example includes an apparatus that includes a plurality of input/output (I/O) ports and a body portion. The plurality of I/O ports can be arranged at a plurality of peripheral surfaces of the body portion. The body portion includes a solid dielectric material having a substantially constant index of refraction. The body portion also includes parallel planar surfaces spaced apart by and bounded by the plurality of peripheral surfaces. The solid dielectric material in the body portion can be writable via a laser-writing process to form an optical waveguide extending between a set of the plurality of I/O ports.

摘要： Compact photonics platforms and methods of forming the same are provided. An example of a compact photonics platform includes a layered structure having an active region along a longitudinal axis, a facet having an angle no less than a critical angle formed at at least one longitudinal end of the active region, and a waveguide having at least one grating coupler positioned in alignment with the angled facet to couple light out to or in from the waveguide.

摘要： An example device in accordance with an aspect of the present disclosure includes a diamond waveguide disposed on a substrate. The substrate includes a dielectric material. A tuner is to extend from the substrate, and is disposed at least in part over the waveguide. The tuner includes a tuner electrode to control a variable distance between the tuner and the waveguide to vary an effective refractive index of the waveguide.

摘要： In the examples provided herein, an optical logic gate includes multiple couplers, where no more than two types of couplers are used in the optical logic gate, and further wherein the two types of couplers consist of: a 3-dB coupler and a weak coupler with a given transmission-to-reflection ratio. The optical logic gate also includes a first resonator, wherein the first resonator comprises a photonic crystal resonator or a nonlinear ring resonator, wherein in operation, the first resonator has a dedicated continuous wave input to bias a complex amplitude of a total field input to the first resonator such that the total field input is either above or below a nonlinear switching threshold of the first resonator, where the optical logic gate is an integrated photonic circuit.
