    Abstract: 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.

    Abstract: In the examples provided herein, an apparatus has a mode converter coupled to a first waveguide to convert light propagating in a first set of spatial modes along the first waveguide to a second set of spatial modes. The apparatus also has a second waveguide coupled to the mode converter, where the second set of spatial modes propagate along the second waveguide in a first direction away from the mode converter. Further, the apparatus includes a coupler to couple a portion of the light propagating in the second set of spatial modes out of the second waveguide. Additionally, the second waveguide has an end facet away from the mode converter to reduce back reflection of the light not coupled out of the second waveguide to the first waveguide.

    Abstract: One example includes an optical fiber interface. The interface includes a first substrate comprising a pair of opposing surfaces. The substrate includes an opening extending therethrough that defines an inner periphery. One surface of the opposing surfaces of the first substrate can be configured to be bonded to a given surface of a second substrate. The interface also includes a plurality of optical fibers secured to the other opposing surface of the first substrate and extending inwardly from a plurality of surfaces of the inner periphery at fixed locations to align the set of optical fibers to optical inputs/outputs (I/O) of an optical system chip that is coupled to the given surface of the second substrate and received through the opening.

    Abstract: A photonic circuit design system includes a photonic circuit design tool to facilitate user inputs to generate a photonic circuit netlist comprising a photonic design component of a photonic circuit design. The system includes a memory system to store the photonic circuit netlist and a component library comprising a plurality of predetermined photonic design components from which the photonic design component is selected. The component library further includes physical data associated with physical characteristics of the plurality of predetermined photonic design components. The system further includes a photonic circuit generator to access the photonic circuit netlist from the memory and the associated photonic design component from the component library based on the photonic circuit netlist and to implement hierarchical algorithm associated with a physical layout and an optical interconnection of the photonic design component in a photonic circuit package based on the physical characteristics to generate the photonic circuit design.

    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: In example implementations, an apparatus includes a bus waveguide, a plurality of optical gates coupled to the bus waveguide and an injection coupler. The bus waveguide receives a plurality of constraint signals. Each optical gate outputs an internal state via a local phase shift when at least one of the plurality of constraint signals has a wavelength that matches a respective resonant wavelength. The injection coupler combines the at least one of the plurality of constraint signals with additional constraint signals that are injected. An error is detected in a bit of a message when an overall phase shift has occurred to the at least one of the plurality of constraint signals causing a power level to exceed a power level threshold of an optical gate when the at least one of the plurality of constraint signals constructively interferes with the additional constraint signals that are injected.
