Abstract: A photonic integrated circuit package includes two arrays or sets of integrated comb laser modules that are bonded to a silicon interposer. Each comb laser of an array has a common or overlapping spectral range, with each laser in the array being optically coupled to a local optical bus. The effective spectral range of the lasers in each array are different, or distinct, as to each array. An optical coupler is disposed within the silicon interposer and is optically coupled to each of the local optical buses. An ASIC (application specific integrated circuit) is bonded to the silicon interposer and provides control and operation of the comb laser modules.

Abstract: An optical logic gate decision-making circuit that combines non-linear materials, such as silicon nitride, on a silicon-on-insulator (SOI) substrate is described. Circuitry includes a ring cavity coupled to an input optical bus waveguide. The input optical bus waveguide receives an optical signal and passes the optical signal to the ring cavity. An electro-optical device, for instance a PN junction, is integrated within the ring cavity to modulate the optical signal such that an optical logic gate function is enabled. An output optical bus waveguide is also coupled to the ring cavity, which outputs the optical signal modified based on the optical logic gate function and based on a wavelength routing function. By using silicon nitride, the optical non-linearity of the materials enables an “all-optical” logic gate. Thus, the optical logic gate decision-making circuit is suitable for all-optical circuits, and support ultrafast optical signal processing and enabling packet switching of data.

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.
