Abstract
Described herein is a wavelength selective switch (100), comprising an input array (102) of optical fibers. The array (102) comprises two or more columns of fibers that are spatially offset in one or both of a switching dimension or a dispersive dimension of the wavelength selective switch (100). Each column (102A, 102B) of fibers is adapted to project respective optical beams. A switching engine (112) is positioned to receive the optical beams and apply an angular switching to the beams to direct the beams to respective output fibers. The optical beams are encoded at respective angles or polarization states such that each column of optical beams is incident onto a different region of the switching engine (112).
