    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: In example implementations, an apparatus includes a plurality of nodes, a pump coupled to the plurality of nodes and a connection network. In one example, each one of the plurality of nodes may store a value. The pump provides energy to the each one of the plurality of nodes. 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. The Ising problem may be solved by the value stored in each one of the plurality of nodes at a minimum energy level.

    Abstract: In one example, an apparatus includes e first beam splitter having a final output and a second output. A first optical waveguide is coupled to the first output, and a second optical waveguide is coupled to the second output. A first tunable phase delay is further coupled to the second optical waveguide and has a third output. A first set of phase modulators is coupled to the first optical waveguide, and a second set of phase modulators is coupled to the third output of the first tunable phase delay. At least one of the first set of phase modulators and the second set of phase modulators includes a phase modulator that is driven to three or more distinct phase states. A second beam splitter has a first input coupled to the first optical waveguide and a second input coupled to the second optical waveguide.

    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.
