Abstract
Described herein are systems and methods of enhancing channel bandwidth in an optical system having a number of wavelength selective switching (WSS) devices. The method includes the steps of passing the optical signals through the WSS devices by: (i) spatially dispersing the wavelength channels of the optical signals; (ii) projecting the spatially dispersed channels onto corresponding predetermined regions of an optical manipulation matrix including a plurality of individually addressable manipulating elements; (iii) determining a modification function that specifies a state for each manipulating element within the predetermined region; and (iv) driving the elements of the corresponding regions at states specified by the function to selectively modify the channel band shape such that the received channel's bandwidth is substantially enhanced, and to spatially direct the wavelength channels to predetermined output ports of the WSS devices.
