Abstract
The present invention is directed towards dynamic spectral shaping. Using a grating, the spectral band is spread across a MEMS or other suitable device array. The device may be the deformable grating modulator invented by Bloom et. al. (U.S. Pat. No. 5,311,360) or other suitable device. The invention also includes the coupling in and out of the fiber and may use polarization optics to ensure the grating is used in only one polarization where the diffraction efficiency is higher.
