Abstract
An integrated 1×K wavelength-selective cross connect (WSC) comprises a demultiplexer arranged to couple each of the N individual wavelength in an input optical WDM signal to a different one of N demultiplexer outputs. Each of N planar beam steerers, arranged along the left edge of a free space region, receives and directs a different one of the N light beams from the demultiplexer to a location on the right edge of the free space region. Each of K gratings arranged along a different location on the right edge of the free space region multiplexes together any light beam received at that location. The 1×K WSC can be implemented with or without the use of crossovers.
