    摘要： This invention pertains to fiber termination combination which includes an optical fiber having a fiber core for transmitting a highly energetic optical signal that can damage the fiber and a structured region around the core for directing the optical signal into the core, the structured region being characterized by multiple channels of smaller internal diameter than the core defined by thin walls disposed around said core; a ferrule, with an opening therein for locating said fiber, at the end of said fiber enveloping said fiber extremity which cooperates with said blocking structure to block the optical signal from impinging on said microstructured region of said fiber; and a blocking structure disposed over the end of said fiber with an opening mating with said fiber core, said blocking structure blocking the optical signal from impinging on said microstructured region of said fiber.

    摘要： Fiber optic amplification in a spectrum of infrared electromagnetic radiation is achieved by creating a chalcogenide photonic crystal fiber (PCF) structure having a radially varying pitch. A chalcogenide PCF system can be tuned during fabrication of the chalcogenide PCF structure, by controlling, the size of the core, the size of the cladding, and the hole size to pitch ratio of the chalcogenide PCF structure and tuned during exercising of the chalcogenide PCF system with pump laser and signal waves, by changing the wavelength of either the pump laser wave or the signal wave, maximization of nonlinear conversion of the chalcogenide PCF, efficient parametric conversion with low peak power pulses of continuous wave laser sources, and minimization of power penalties and minimization of the need for amplification and regeneration of pulse transmissions over the length of the fiber, based on a dispersion factor.

    摘要： An N port fiber optical switch includes a movable housing having a perimeter and N corners; a plurality N of optical fibers positioned within the housing and inside the perimeter; and a plurality N of actuators, wherein each actuator is positioned on a corresponding corner such that when selectively activated one or more of the actuators urges the movable housing and the plurality of optical fibers to a selected switch position. The switch provides short switching times and high power handling while allowing for a large number of ports and provides the capability of interfacing with and switching between a variable number of ports.
