Abstract

See full text

A wavelength selective switch (WSS) may include a first port array including input ports, each to launch a respective beam of light, and a dispersive element to separate, in a lateral direction, a beam of light, launched by one of the input ports, into dispersed wavelength channel sub-beams. The WSS may include a switching array to direct the dispersed wavelength channel sub-beams, at respective angles in a vertical direction. The dispersive element may converge groups of dispersed wavelength channel sub-beams in the lateral direction to form wavelength channel sub-beams. The WSS may include a splitting element to split, in the lateral direction, a wavelength channel sub-beam, of the wavelength channel sub-beams, into split wavelength channel sub-beams. The WSS may include switching elements to direct the split wavelength channel sub-beams at respective angles in the vertical direction, and output ports associated with the switching elements.
