摘要： A wavelength division multiplexed (WDM) reconfigurable optical switch. The switch has a set of arrays of optical beam connections, each comprising an array of optical outputs and having an optical input to receive a WDM input optical signal; a first diffractive element to demultiplexed the WDM input optical signal into a plurality of demultiplexed optical input beams, and to disperse said demultiplexed optical input beams spatially along a first axis; first relay optics between the set of arrays of optical beam connections and the first diffractive element; and a reconfigurable holographic array comprising a 2D array of reconfigurable sub-holograms defining sub-hologram rows and columns. The arrays of said set of arrays and the sub-hologram rows and columns are arranged and aligned in particular ways so that wavelength channels of the WDM input signal for each array can be steered within the device towards a selected optical output.

摘要： 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 centres 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.

摘要： An optic switch for cross-connecting input light signals incoming from inlet fiber cables to outlet fiber cables is disclosed that makes use of a holographic filter (5) having a series of preformed different speckle patterns, each in the form of a hologram (H1, H2, . . . ). Associated with input light signals guided past respective inlet passages (4in) of a multimode waveguide (4), different speckle patterns are formed by applying different control voltages across respective electrode pairs (10, 10a) provided thereon. These speckle patterns past a single outlet passage (4out) of the multimode waveguide (4) into which the inlet passages (4in) converge are joined together and enter the holographic filter (5) in which an input light signal is selectively switched, addressed and cross-connected to an outlet waveguide (2) through a region thereof where a formed speckle pattern coincides with a preformed speckle pattern. The multi mode waveguides (4) is formed in, e.g., a LiNbO3 photorefractive substrate (3).

摘要： To operate an optical device comprising an SLM with a two-dimensional array of controllable phase-modulating elements groups of individual phase-modulating elements are delineated, and control data selected from a store for each delineated group of phase-modulating elements. The selected control data are used to generate holograms at each group and one or both of the delineation of the groups and the selection of control data is/are varied. In this way upon illumination of the groups by light beams, light beams emergent from the groups are controllable independently of each other.

摘要： 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.
