Abstract: An arrayed waveguide grating (AWG) based multi-core and multi-wavelength interconnection network, comprising N upper-level switches, N lower-level switches, and a network intermediate stage, with each upper- and lower-level switches has N CWDM optical transceiving modules. The N optical transceiving modules of each upper-level switch is connected with n m×1 multi-core optical multiplexing modules, the N optical transceiving modules of each lower-level switch is connected with n 1×m multi-core demultiplexing modules, the network intermediate stage is comprised of n2 r×r multi-core and multi-wavelength wiring modules. The upper-level multi-core optical multiplexing modules, the lower-level multi-core demultiplexing modules, and the n2 r×r multi-core and multi-wavelength wiring modules of the network intermediate stage are connected via an m-core MPO-MPO optical fiber jumper. The wiring complexity of the interconnection network is O(N2/r), with employment of a wavelength set of Λ={λ0, . . . , λk-1}. The present invention conserves wavelength resources of communication windows, enhances scalability of the AWG based interconnection network, while reduces network wiring complexity.

Abstract: As photonics evolves closer and closer to the electronic processing elements in order to meet the demands of speed, latency of evolving data communications networks and data centers the inventors, rather than seeking direct monolithically integrated CMOS based processing photonic and electronic elements, have established a different route. Namely replace the computer hubs/electrical bridges interconnecting the multiple core logic chipset elements with a photonic bridge. In this manner high risk chip-to-chip photonic point-to-point links are replaced with photonic SOCs that leverage photonics bandwidth density attribute rather than its bandwidth distance attributes. An SOI based Electronic Embedded Photonic Switching Fabric is presented supporting, for example, N×MGb/s interconnections exploiting N channels of MGb/s wherein each channel of exploits S WDM channels of TGb/s. Embodiments of the invention also support high density optical interconnection via vertical grating couplers and multicore fibers.

Abstract: A spectral-temporal connector interconnects a large number of nodes in a full-mesh structure. Each node connects to the spectral-temporal connector through a dual link. Signals occupying multiple spectral bands carried by a link from a node are de-multiplexed into separate spectral bands individually directed to different connector modules. Each connector module has a set temporal rotators and a set of spectral multiplexers. A temporal rotator cyclically distributes segments of each signal at each inlet of the rotator to each outlet of the rotator. Each spectral multiplexer combines signals occupying different spectral bands at outlets of the set of temporal rotators onto a respective output link. Several arrangements for time-aligning all the nodes to the connector modules are disclosed.

The method may further include transmitting, by the optical device, a second channel. The second channel may have a second set of subcarriers. The second channel may be attenuated during transmission by the filter associated with the wavelength selective switch. The first channel and the second channel being included in a super-channel. The first set of subcarriers may be selected based on a first signal quality factor associated with attenuation of the first set of subcarriers by the filter.
