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.
