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: A first system is associated with an operating status. A second system is to affect the operating status based on usage of a shared resource. A restrictor is to control usage of the shared resource. A controller is to adjust the restrictor to control usage of the shared resource based on the operating status and a received communication indicating a resource status.
