摘要： The present invention relates to an articulated micro-electro-mechanical (MEMS) device, which is constructed in such a way as to enable several of the devices to be closely packed together, i.e. high fill factor, for redirecting specific wavelengths of light from a dispersed optical signal to different output ports. The articulated MEMS device includes multiple pivotally connected sections that are pivotable about two perpendicular axes for limiting the amount of dynamic cross-talk as the device is rotated between different positions.

摘要： A control system is designed to control an optical cross-connect having a switch core defined by first and second independently movable beam deflectors capable of selectively defining an optical path between a pair of ports of the optical cross-connect. An optical element having optical power is arranged in a propagation path of light beams between the first and second beam deflectors. The control system includes a pilot light source, an optical sensor associated with each beam deflector, and a feedback path. The a pilot light source inserts a pilot light into the switch core colinearly with live traffic. The optical sensor detects a predetermined geometric property of the pilot light emerging from the switch core. This predetermined geometric property is unambiguously associated with an angular position of the associated beam deflector. The feedback path actively controls a position of the associated beam deflector based on the detected geometric property.

摘要： A wavelength blocker including an input port for launching an input beam of light, first dispersing means for dispersing the input beam of light according to wavelength, an array of independently addressable elements for selectively blocking a portion of the dispersed beam of light, second dispersing means for receiving the passed dispersed beam of light and for producing a single multiplexed beam of light therefrom, and an output port for transmitting a modified output beam of light. The array of independently addressable elements are designed such that the wavelength blocker is capable of blocking a variable number of non-consecutive channels without significantly affecting the unblocked channels.

摘要： A wavelength cross connect is provided in which there is a dispersive arrangement per port for each input port and each output port. Some of the dispersive arrangements have differing characteristics so as to result in different performances at the ports. The dispersive arrangements can differ in the selection of different dispersive elements or differing coupling optics. A particular implementation features a first set of waveguide dispersive elements having first performance characteristics, and a second set of waveguide dispersive elements having second performance characteristics.

摘要： An array of dispersive arrangements, for example an array of waveguide dispersive elements, is compensated with a set of optical compensators such as wedges or pairs of cylindrical lenses. The optical compensators are selected to achieve a pre-defined dispersion profile across the array of waveguide dispersive elements. The optical compensators can make corrections for fabrication errors or other errors in an optical system that includes the array of waveguide dispersive elements. A particular application is found in waveguide selective switches.
