The connection network may include a two dimensional array of elements, wherein each group of the two dimensional array of elements is in communication with a respective one of the plurality of nodes, wherein the connection network may be tuned with parameters associated with encoding of an Ising problem. The connection network may process the value stored in each one of the plurality of nodes.

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.

摘要： Examples described herein relate to an optical switching device wherein a racetrack resonant structure is positioned to determine a frequency passband by coupling. In some examples, a first waveguide receives an input light signal. A second waveguide is positioned to enable the input light signal to couple between the first waveguide and the second waveguide through a first coupling gap. The racetrack resonant structure is positioned adjacent to the first coupling gap to enable the input light signal to couple between one of the first waveguide and the second waveguide and the racetrack resonant structure through a second coupling gap. Thus, the racetrack resonant structure is to determine the frequency passband such that a first portion of the input light signal that coincides with the frequency passband is output by the first waveguide, and a second portion of the input light signal that does not coincide with the frequency passband is output by the second waveguide.

摘要： Examples described herein relate to concurrently performing operations on optical signals. In an example, a method includes providing, to an optical circuit, a first plurality of signals having a first optical property and encoding a first vector. A second plurality of signals is provided to the circuit that encodes a second vector and has a second optical property that is different from the first optical property. A first attribute-dependent operation is performed on the first plurality of signals via the circuit to perform a first matrix multiplication operation on the first vector, and concurrently, a second attribute-dependent operation is performed on the second plurality of signals to perform a second matrix multiplication operation on the second vector. The first matrix multiplication operation and the second matrix multiplication operation are different based on the first optical property being different from the second optical property.

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： In example implementations, an optical gate is provided. The optical gate receives at least one optical signal via a waveguide of an optical memory gate. The optical gate compares a wavelength of the at least one optical signal to a resonant wavelength associated with a resonator. When the wavelength of the at least one optical signal matches the resonant wavelength, a value that is stored in the resonator is read out via the at least one optical signal. Then, the at least one optical signal with the value that is read out is transmitted out of the optical gate.
