1. A multi-port wavelength selective switch comprising:

  • a one dimensional array of input and output ports;

    a wavelength dispersive element configured to receive input optical signals from the input ports, and to disperse wavelength components thereof; and

    an array of beam steering devices, each of which is controllable to a position at which the beam steering device directs a wavelength component of an input optical signal received through a first input port to an output port and directs the same wavelength component of an input optical signal received through a second input port away from all of the output ports.
