ABSTRACT:
One embodiment disclosed relates to a method for wavelength-selective switching and equalization. The method includes dispersing an incoming multiplexed signal into wavelength components, focusing the wavelength components onto different portions of a controllable light diffractor array, and controllably diffracting each wavelength component such that each said component is individually attenuated and arrives at the individually selected output without substantial crosstalk between the outputs. Another embodiment relates to a wavelength-selective switching device with integrated equalizer functionality. Another embodiment relates to an optical apparatus for wavelength-selective switching and equalization. The apparatus includes a means for controllably diffracting each wavelength component of a multiplexed input such that each said component is controllably attenuated and directed to arrive at an individually selected output.
