Abstract
One embodiment pertains to an apparatus for wavelength-selective switching and equalization of an incoming multiplexed signal having a plurality of wavelength components. The apparatus includes a first controllable light modulator, a second controllable light modulator, and a lens system. The first controllable light modulator controllably deflects a first set of the wavelength components and controllably reflects a second set of the wavelength components. The wavelength components in the second set are mapped onto separate sections of the second controllable light modulator by the lens system and are controllably reflected by the second controllable light modulator.
