Abstract
An optical switching device has multiple input ports and multiple output ports and is capable of switching a wavelength component from any of the input ports to any of the output ports. The optical switching device is configured with beam steering arrays that are controlled to provide the switching from any of the input ports to any of the output ports. The beam steering arrays may be microelectromechanical (MEMS) mirror arrays or liquid-crystal on silicon (LCOS) panels. In addition, an array of beam-polarizing liquid-crystal elements provides wavelength-independent attenuation.
