    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: A wavelength selective switch architecture (100) for ROADMs for switching the spectral channels of a multi-channel, multi- wavelength optical signal between input and output ports employs a biaxial MEMS port mirror array (106) for optimal coupling efficiency and ITU grid alignment, an anamorphic beam expander (110) for expanding input optical signals to create an elongated beam profile (146), a diffraction grating (112) for spatially separating the spectral channels, an anamorphic focusing lens system (116), an array (118) of biaxial elongated channel MEMS micromirrors, a built-in Optical Channel Monitor, and an electronic feedback control system. The biaxial channel micromirrors are rotatable about one axis to switch spectral channels between ports, and are rotatable about an orthogonal axis to vary the coupling of the spectral channel to an output port and control attenuation of the spectral signal for complete blocking or for a predetermined power level. The architecture affords hitless switching, near notchless operation, ITU channel alignment, high passband, stability over a broad temperature range, and minimum insertion loss through the optimal coupling efficiency enabled by the feedback control system.

    Abstract: Optical switches can include collimator elements that accommodate two or more optical ports. This increases the number of ports the switch can accommodate without having to increase the size of other optical components within the switch. Separate deflectors can be used to accommodate optical signals from two different groups of ports. In some embodiments cross-coupling of signals between the two groups can be accomplished through use of re-direction optics.

    Abstract: Effects of diffraction of a spectral beam from an edge of the micromirrors are reduced in order to optimize the passband in a wavelength selective switch. The effects of diffraction on the pass band may be reduced by using rotation of the micromirror about both the attenuation axis and the switching axis to achieve the desired level of attenuation. Peak coupling can be attained by dithering the micromirror about a dither axis that is tangent to a contour of constant attenuation using simultaneous rotation about the switching and attenuation axes. A power level of a spectral channel may be attenuated by rotating the channel micromirror with respect to an effective attenuation axis that is non-orthogonal to the dither axis through a combination of rotations about the switching axis and the attenuation axis.

    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.
