Abstract
A device for selectively adjusting power levels of component signals of a wavelength division multiplexed signal including a first wavelength signal and a second wavelength signal. The device includes a light modulator comprising a plurality of elements. The plurality of elements are configured to form an arbitrary phase profile. The plurality of elements includes a first group of elements configured to receive the first wavelength signal and a second group of elements configured to receive the second wavelength signal. The first group of elements and the second group of elements include at least one common element. Each element is controllable such that each group of elements directs a selected portion of a corresponding received wavelength signal in a first mode. Each first mode is collected such that a power level of each wavelength signal is selectively adjusted.
