Wavelength selective switch and equalizer
First Claim
1. A device comprising a light modulator including a plurality of elements wherein each element is selectively operable such that the plurality of elements are dynamically configurable to combine selected ones of a plurality of grating periods such that selected portions of an incident light are directed into one or more distinct modes wherein each distinct mode corresponds to a grating period.

Abstract
A device comprising a light modulator including a plurality of elements wherein each element is selectively operable such that the plurality of elements are dynamically configurable to combine selected ones of a plurality of grating periods such that selected portions of an incident light are directed into one or more distinct modes wherein each distinct mode corresponds to a grating period. The device can be used as a 1×N wavelength selective switch and equalizer where N is the number of output channels.
