Abstract:
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

Claim (Index 20):
A stacked, wavelength division multiplexed (WDM) reconfigurable optical switch, the switch comprising:\n a stacked plurality of clusters of optical connections, each comprising an optical input and a plurality of optical outputs; and a beam-steering spatial light modulator configured to display a plurality of rows of sub-holograms, one per cluster of optical connections, wherein different wavelength components of the optical inputs are dispersed along the rows, and wherein the rows are stacked in the same direction as said clusters of optical connections; and a dispersive optical element on an optical path between said clusters of optical connections and said spatial light modulator to provide said wavelength dispersion; and wherein the switch further comprises: a plurality of lenslet arrays, one per cluster of optical connections, each to couple a respective cluster of optical connections to said spatial light modulator, wherein each lenslet array creates a common plane where input/output beams of the switch overlap at different angles with respect to the optical axis.
