This invention provides a novel wavelength-separating-routing (WSR) apparatus that uses a diffraction grating to separate a multi-wavelength optical signal by wavelength into multiple spectral channels, which are then focused onto an array of corresponding channel micromirrors. The channel micromirrors...http://www.google.fr/patents/USRE39331?utm_source=gb-gplus-shareBrevet USRE39331 - Reconfigurable optical add-drop multiplexers with servo control and dynamic spectral power management capabilities
