Abstract:
A wavelength division multiplexed (WDM) reconfigurable optical switch, the switch has at least one optical input port to receive a WDM input optical signal comprising a plurality of wavelength channels; a plurality of optical output ports; a reconfigurable holographic array on an optical path between the at least one optical input port and the plurality of optical output ports; and at least one diffractive element on an optical path between at least one optical input port and the reconfigurable holographic array, to demultiplex the WDM input optical signal into a plurality of demultiplexed optical input beam channels, and to disperse the demultiplexed optical input beam channels spatially along a first axis on said the reconfigurable holographic array; and the switch further comprises one or more beam profiling optical elements to modify transverse beam profiles of the demultiplexed optical input beam channels.

Claim (Index 18):
A wavelength division multiplexed (WDM) reconfigurable optical switch, the switch comprising:\n at least one optical input port to receive a WDM input optical signal comprising a plurality of wavelength channels; a plurality of optical output ports; a spatial light modulator (SLM) for displaying a reconfigurable holographic array, wherein the SLM is located on an optical path between said at least one optical input port and said plurality of optical output ports; and at least one diffractive element on an optical path between at least one optical input port and said reconfigurable holographic array, to demultiplex said WDM input optical signal into a plurality of demultiplexed optical input beam channels, and to disperse said demultiplexed optical input beam channels spatially along a first axis on said reconfigurable holographic array; wherein said reconfigurable holographic array comprises an array of configurable sub-holograms, said array extending along said first axis, wherein a sub-hologram is configured to direct a demultiplexed optical input beam channel to a respective selected one of said optical outputs; and wherein the switch further comprises: a matched spatial filter in an optical path between at least one optical input port and one or more of said optical output ports, wherein said matched spatial filter imparts a lock phase pattern; an optical data reader to read key phase pattern data from said WDM input optical signal; and a driver coupled to said input to drive said SLM, responsive to said key phase pattern data, to display said array of sub-holograms in combination with a key phase pattern which complements a phase pattern of said lock phase pattern to compensate for said matched filter.
