摘要： A supervisory signal is superimposed onto a high-speed data stream so that the number of optical transceivers needed by an optical network is reduced. The supervisory signal is superimposed onto the high-speed data stream as an in-band modulation of the data stream. To improve signal-to-noise ratio of the in-band supervisory signal, the supervisory signal is first modulated to a higher frequency before it is superimposed onto the high-speed data stream.

摘要： One embodiment of an optical fiber for reducing insertion loss and insertion loss ripple includes a tapered region where the optical fiber has a diameter of approximately 125 microns at a first end and a diameter of approximately 50 microns at a second end. The cladding layer of the tapered region is tapered from the first end towards the second end. This section of the optical fiber may be tapered using an etch process or any other technically feasible process. The tapered configuration enables the distance between the optical axes of two optical fibers inserted into a ferrule to be reduced from approximately 125 microns to approximately 50 microns. Decreasing the distance between the optical axes causes a reduction in both insertion loss and insertion loss ripple.

摘要： A system for a re-configurable optical de-multiplexer, multiplexer or add/drop multiplexer is provided. A re-configurable de-multiplexer system comprises a wavelength selective switch having an input port, an output port and an internal port; a wavelength division de-multiplexer (WDM) optically coupled to the internal port and a plurality of dropped-channel ports optically coupled to the WDM. The wavelength selective switch receives a plurality of input wavelength-division multiplexed channels from the input port and routes a first subset of the channels to the output port and a second subset of channels to the internal port and then to the WDM. The WDM separates each of the dropped channels to a different respective one of the channel ports.

摘要： An optical switching device includes an array of liquid crystal macropixels, wherein each macropixel includes at least two liquid crystal subpixels. The subpixels may be controlled together to act as a single polarizing pixel, or independently to act as multiple polarizing pixels. When the switching device processes a WDM having a wide channel spacing, the subpixels are controlled together, and when the switching device processes a WDM having a narrow channel spacing, each subpixel is controlled independently.
