摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： This invention provides a novel method and apparatus which use a wavelength-dispersing means such as a diffraction grating to spatially separate a multi-wavelength optical signal along with a reference signal by wavelength into multiple spectral channels and a reference spectral component in a spectral array with a predetermined relative alignment. By aligning the reference spectral component at a predetermined location, the spectral channels simultaneously impinge onto designated locations, e.g., on an array of beam-receiving elements positioned in accordance with the spectral array. The reference spectral component may be further maintained at the predetermined location by way of servo-control, thereby ensuring that the spectral channels stay aligned at the designated locations. The present invention can be used to construct a new line of servo-based optical systems, including spectral power monitors and optical multiplexers/demultiplexers, for WDM optical networking applications.

摘要： An optical apparatus can include an optical port array having an MxN array of fiber collimator ports. The array of ports is configured such that there is a gap within each column of ports located between two rows of ports. The gap is wide enough to permit a hitless beam switching trajectory to pass between the two rows of ports from one side of the array of ports to an opposite side.
