摘要： A wavelength selective switch architecture 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 for optimal coupling efficiency and ITU grid alignment, an anamorphic beam expander for expanding input optical signals to create an elongated beam profile, a diffraction grating for spatially separating the spectral channels, an anamorphic focusing lens system, an array of biaxial elongated channel MEMS micromirrors, a built-in Optical Channel Monitor, and an electronic feedback control system. The bi-axial 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 optical coupling efficiency enabled by the feedback control system.

摘要： A variable optical source (801) to selectively provide a desired optical output signal in response to a control signal is provided. The optical source includes an optical filter that attenuates a broadband optical input signal or a multi-spectral input signal (802). The optical filter is controllable or programmable to selectively provide a desired filter function. The optical filter (10) includes a spatial light modulator (36), which may comprise an array of micromirrors (52) that effectively forms a two-dimensional diffraction grating mounted in a retro-reflecting configuration. The input optical signal is dispersed onto the array of micromirrors (52) along a spectral axis or direction (55) such that input light is spread over a plurality of micromirrors to effectively pixelate the light. The broadband light or signals of the multi-spectral input light is selectively attenuated by flipping or tilting a selected number of micromirrors to thereby deflect a portion of the incident radiation away from the return optical path. The micro-mirrors operate in a digital manner by flipping between a first and second position in response to a control signal (56) provided by a controller (58) in accordance with an attenuation algorithm and an input command (60).

摘要： For systems which disperse individual wavelength components of a DWDM beam into an array of converging beams, the individual wavelength signals are modified for blocking, equalization or other purposes by reflective liquid crystals cells. Thus modulated or modified components are then recombined by the system into an output beam, as by reverse passage through the system. Controlled full extinction or linear attenuation may be introduced by converging asymmetrical beams of separate polarization components for each wavelength into superposed relation on zero twist nematic crystal cells which are voltage controlled so as to retard for extinction of greater than 40 dB or to transform the state of polarization to a selected angle for attenuation. Polarization sensitive elements in the return paths of the reflected beams then filter the rejected components.

摘要： A wavelength router that selectively directs spectral bands between an input port (12) and output ports (15). The router includes a free-space optical train disposed between the input ports and said output ports, and a routing mechanism (30). The free-space optical train can include air-space elements (20, 25) or can be monolithic construction. The optical train includes a dispersive element (25) such as a diffraction grating, and is configured so that the light from the input port encounters the dispersive element twice before reaching the output ports. The routing mechanism (30) includes one or more routing elements and cooperates with the other elements (37) in the optical train to provide optical paths that couple subsets of the spectral bands to desired output ports.
