摘要： A dispersion compensator having relatively uniform transmission characteristics over the bandwidth of a communication channel. The compensator is designed to process an optical signal corresponding to the communication channel by decomposing that signal into spectral components, routing different components along different optical paths that impart relative delays between the components, and recombining the delayed components spatially and directionally to generate a processed optical signal with reduced chromatic dispersion. In one embodiment, the compensator is a waveguide circuit that includes four diffraction gratings operating in transmission and optically coupled to a tunable lens array, in which different tunable lenses receive light corresponding to different communication channels. For each channel, a desired group delay value is produced by selecting magnification strength of the corresponding tunable lens.

摘要： An optical MEMS devices is imaged to a different location at which a second optical MEMS device is located in a manner that effectively combines the tilt angles of at least one micro mirror of each of the first and second optical devices. The imaging system may reproduce the angle of reflection of the light from the first micro mirror. This may be achieved using a telecentric system, also known as a 4 f system, as the imaging system. The physical size of the arrangement may be reduced by compacting the optical path, e.g., using appropriate conventional mirrors, and/or employing folded arrangements, i.e., arrangements in which there is only one MEMS device stage that does double duty for both input and output through the use of at least one conventional mirror.

摘要： A method or apparatus for use in generating an information system, wherein an object-oriented model of the information system is provided, the model defining classes of information objects require to be supported by the information system in terms of their attributes, operations that maybe performed on the object, and an intended relationship (if any) between two or more of the objects. Built-in or predefined descriptions of the operations which maybe performed on the objects are provided in terms of conditions that should hold initially, data that might be affected, and the desired results. An operation referenced in a class definition is then automatically expanded by adding a respective built-in or predefined description thereto within the object-oriented model of the information system. It is determined if the attributes of any other class defined within the model would be affected by the operation and, if so, the operation is automatically further expanded to include an update function to update one or more attributes determined to be affected by the operation accordingly.

摘要： A device employing at least one wavelength sieve/combiner that operates on discrete wavelength units and is optically interposed between an array of fibers and an array of micro mirrors which may be configured to act as in a multiplexing mode, a demultiplexing mode, a broadcast mode, and combinations of such modes. Each wavelength sieve/combiner can split a wavelength division multiplexed (WDM) beam into various discrete wavelength unit beams, combine various discrete wavelength unit beams into a WDM beam, or cause multiple copies of part or all of the wavelengths to be supplied as outputs. Typically, each fiber is associated with one wavelength sieve/combiner. Preferably, the beams between a wavelength sieve/combiner and the micro mirror array should be converging to the plane of the micro mirror array.
