Abstract
A M×N wavelength selective optical switch (WSS) for switching K wavelength channels is disclosed. The WSS has two MEMS micromirror arrays, a M×K array and a 1×N array, for switching any wavelength channel from any input port to any output port, provided that any output port receives optical signals from only one input port. The WSS can be used to build fully reconfigurable, colorless and directionless node of an agile optical network.
