Abstract
This invention provides a wavelength-separating-routing (WSR) apparatus that uses a diffraction grating to separate a multi-wavelength optical signal by wavelength into multiple spectral channels that are communicated to an array of channel micromirrors, and which includes a micromirror position sensing unit to monitor the position of each of the channel micromirrors. The micromirror position sensing unit may include an array of position sensitive detectors or split detectors, which each receive a diverted fraction of one of the reflected spectral channels.
