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 19):
A method as claimed in  14 , further comprising:\n providing a second set of optical port arrays, each comprising an output port and a set of input ports, wherein said second set of optical port arrays is spatially dispersed along a fourth axis; coupling each set of output ports of said set of port arrays to said input ports of said second set of port arrays; providing light from said input ports of said second set of port arrays to a diffractive element to provide dispersion along a third axis orthogonal to said fourth axis; providing said dispersed light from said input ports of said second set of port arrays to a second reconfigurable holographic array comprising a 2D array of reconfigurable sub-holograms defining sub-holograms rows aligned with said third axis and sub-hologram columns aligned with said fourth axis; and steering the dispersed light from each input port of a port array of the second set of port arrays, in two dimensions using said second reconfigurable holographic array, towards the output port for the port array.
