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: A photonic node includes a first circuit disposed on a first substrate and a second circuit disposed on a second substrate different from the first substrate. The first circuit is configured to route light signals originated from the photonic node to local nodes of a local group in which the photonic node is a member. The second circuit is configured to route light signals received from a node of an external group in which the photonic node is not a member, to one of the local nodes.

Abstract: A method includes: receiving a packet in an optical domain, the packet including a data payload and a routing header indicative of a routing sequence for the data payload; reading a first bit of the routing header to make a routing decision for the data payload; stripping the first bit of the routing header in the optical domain to generate an updated routing header; and routing the data payload and the updated routing header based on the routing decision.

Abstract: An optical transceiver module includes a light source configured to emit light, a transmitter resonator configured to transmit light signals from the light source, a temperature sensor configured to detect temperatures of the transmitter resonator, and a controller circuit. The controller circuit is configured to obtain a first temperature variation value based on the detected temperatures, and encode the first temperature variation value via the transmitter resonator in an outgoing data stream.

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.
