    Abstract: An photonic circuit includes a substrate, a plurality of first light waveguides disposed on the substrate, the first light waveguides extending in a first direction, a plurality of second light waveguides disposed on the substrate and extending in a second direction intersecting the first direction, and a plurality of first micro-ring resonators disposed on the substrate. Each of the first light waveguides has an intersection with each of the second light waveguides. Each of the intersections is provided with a first micro-ring resonator of the first micro-ring resonators. Each first micro-ring resonator is configured to route signals of a respective wavelength from one of the light waveguides at the intersection to another light waveguide at the intersection.

    Abstract: Systems and methods are provided for zero-added latency communication between nodes over an optical fabric. In various embodiments, a photonic interface system is provided that comprises a plurality of optical routing elements and optical signal sources. Each node within a cluster is assigned an intra-cluster wavelength and an inter-cluster wavelength. All the nodes in a cluster are directly connected and each node in a cluster is directly connected to one node in each of the plurality of clusters. When an optical signal from a different cluster is received at a node serving as the cluster interface, the photonics interface system allows all wavelength signals other than the node's assigned wavelength to pass through and couple those signals to an intra-cluster transmission signal. Zero latency is added in rerouting the data through an intermediate node.

    Abstract: Embodiments of the present disclosure provide etch-variation tolerant optical coupling components and processes for making the same. An etch-variation tolerant geometry is determined for at least one waveguide of an optical coupling component (e.g., a directional coupler). The geometry is optimized such that each fabricated instance of an optical component design with the etch-variation tolerant geometry has substantially the same coupling ratio at any etch depth between a shallow etch depth and a deep etch depth.
