    Abstract: PROBLEM TO BE SOLVED: To provide a new 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. SOLUTION: In the wavelength-separating-routing (WSR) 100, the channel micromirrors 103 are individually controllable and continuously pivotable to reflect the spectral channels into multiple output ports. As such, the WSR apparatus is capable of routing the spectral channels on a channel-by-channel basis and coupling any spectral channel into any one of the output ports. The WSR apparatus of the present invention may be further equipped with servo-control and spectral power-management capabilities, thereby maintaining the coupling efficiencies of the spectral channels into the output ports at desired values. The WSR apparatus of the present invention can be used to construct a new class of dynamically reconfigurable optical add-drop multiplexers (OADMs) for wavelength-division-multiplexing (WDM) optical networking applications.

    Abstract: This invention provides a novel wavelength-separating-routing (WSR) apparatus that uses a diffraction grating (101) to separate a multi-wavelength optical signal by wavelength into multiple spectral channels, which are than focused onto an array of corresponding channel micromirrors (220). The channel micromirrors are individually controllable and continuously pivotable to reflect the spectral channels into multiple output ports. As such, the inventive WSR apparatus is capable of routing the spectral channels on a channel-by-channel basis and coupling any spectral channel into any one of the output ports. The WSR apparatus of the present invention may be further equipped with servo-control and spectral power-management capabilities, thereby maintaining the coupling efficiencies of the spectral channels into the output ports at desired values.

    Abstract: A method and apparatus for optical spectral power monitoring using a time-division-multiplexed detection scheme. The apparatus uses a wavelength-dispersing means (120) such as a diffraction grating to separate an optical signal into multiple spectral channels, and an array of beam-manipulating elements (140) positioned to correspond with the spectral channels. The beam-manipulating elements are individually controllable so as to direct the spectral channels into an optical detector (150) in a time-division-multiplexed sequence. The apparatus may further employ a polarization diversity scheme for polarization-insensitive operation. This enhances the spectral resolution of the apparatus while providing improved accuracy in spectral power detection. Spectral power monitors constructed according to the present disclosure are well-suited for WDM optical networking applications.
