Abstract: 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.

Abstract: 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.

Abstract: A method for determining a solution to a constrained optimization problem includes programming a weights matrix of a Hopfield network with a first encoded matrix representation of an initial constrained optimization problem. The method also includes employing the Hopfield network to determine a solution to the initial constrained optimization problem. Additionally, the method includes encoding a plurality of constrained optimization problems associated with a target constrained optimization problem into a plurality of encoded matrix representations each of which are a combination of the first and the second encoded matrix representations. The plurality of encoded matrix representations increases in convergence to the second encoded matrix representation of the target constrained optimization problem sequentially. The method further includes re-programming the weights matrix of the Hopfield network in an iterative manner with the plurality of encoded matrix representations.

Abstract: Staged neural networks and methods are described herein. In some embodiments, the methods may identify a plurality of second NP hard/complete problems that are similar to the first NP hard/complete problem and identify solutions to the second NP hard/complete problems. The methods may train a deep neural network with the second NP hard/complete problems and the solutions. The methods may provide the first NP hard/complete problem to the trained deep neural network to generate a preliminary solution to the first NP hard/complete problem and provide the preliminary solution to a recursive neural network configured to execute an energy minimization search. The recursive neural network may generate a final solution to the problem based on the preliminary solution.

Abstract: Systems and methods for an optical ternary content addressable memory (TCAM) are provided. The optical TCAM implements a time-division multiplexing (TDM) based encoding scheme to encode each bit position of a search word in the time domain. Each bit position is associated with at least two time slots. The encoded optical signal comprising the search word is routed through one or more modulators configured to represent a respective TCAM stored word. If a mismatch between at least one bit position of the search word and at least one TCAM stored word occurs, a photodetector or photodetector array will detect light.

Abstract: Systems and methods for an optical ternary content addressable memory (TCAM) is provided. In various embodiments, one or more search words can be encoded in a multi-wavelength input signal. Each bit position associated with a set of wavelengths of the input signal, each wavelength corresponding to a logic value. A plurality of copies of the input signal can be coupled to an optical search engine comprising a plurality of rows of stored words. In various embodiments, the search word may be encoded in the amplitude of a single wavelength. Each bit position can be associated with a set input waveguides, and a logic value can be encoded based on whether amplitude of the associated wavelength is detected on a respective input waveguide of the set of waveguides. A mismatch of at least one bit is indicated if light is detected on an output of the optical TCAM.

Abstract: Examples herein relate to single-etch layer grating couplers. In particular, implementations herein relate to single-etch layer grating couplers comprising a planar waveguide wherein a first grating section and a second grating section are etched into. The first grating section is configured to scatter light at a given wavelength at a first angle relative to vertical and the second grating section is configured to scatter light at the given wavelength at a second angle relative to vertical. The stagger-tuning of the first grating section and the second grating section results in the light at the given wavelength being scattered at a desired angle the same or near an angle at which an optical fiber is offset from vertical.
