摘要： A method for obtaining transient Bragg gratings in optical waveguides and several different applications of the transient Bragg gratings obtained using this method are presented. The basic mechanisms for obtaining the transient gratings in the waveguides are refractive index change due to Kerr nonlinearity, free carrier generation, and gratings formed by linear or non-linear absorption of thermal energy. The exemplary applications include an ultra-fast fiber laser source at any central wavelength, a fast spectral switch/modulator, transient pulse stretchers based on transient chirped gratings, Q-switching based on transient gratings, and time reversal of ultra-short pulses and low power sub-nanosecond pulse generations.

摘要： Certain example embodiments relate to an improved method of strengthening glass substrates (e.g., soda lime silica glass substrates). In certain examples, a glass substrate may be chemically strengthened by creating an electric field within the glass. In certain cases, the chemical tempering may be performed by surrounding the substrate by a plasma including certain ions, such as Li+, K+, Mg2+, and/or the like. In some cases, these ions may be forced into the glass substrate due to the half-cycles of the electric field generated by the electrodes that formed the plasma. This may advantageously chemically strengthen a glass substrate on a substantially reduced time scale. In other example embodiments, an electric field may be set in a float bath such that sodium ions are driven from the molten glass ribbon into the tin bath, which may advantageously result in a stronger glass substrate with reduced sodium content.

摘要： Devices and methods for optical-fiber processing for connector applications are disclosed, wherein the devices and methods utilize a quantum cascade laser operated under select processing parameters to carry out end face polishing. The method includes supporting the optical fiber in a ferrule so that a bare end section of the fiber protrudes from an end of the ferrule by a protrusion distance. The method then includes irradiating the end face with light from the quantum cascade laser to polish the end face. The quantum cascade laser can also be used to form a bump in a central portion of the end face, wherein the bump facilitates physical contact between respective end faces of connected optical fibers.

摘要： The present invention relates to a fiber having a core of crystal fiber doped with chromium and a glass cladding. The fiber has a gain bandwidth of more than 300 nm including 1.3 mm to 1.6 mm in optical communication, and can be used as light source, optical amplifier and tunable laser when being applied for optical fiber communication. The present invention also relates to a method of making the fiber. First, a chromium doped crystal fiber is grown by laser-heated pedestal growth (LHPG). Then, the crystal fiber is cladded with a glass cladding by codrawing laser-heated pedestal growth (CDLHPG). Because it is a high temperature manufacture process, the cladding manufactured by this method is denser than that by evaporation technique, and can endure relative high damage threshold power for the pumping light.

摘要： A refractory dielectric body is heated with a plasma fireball at conditions which do not result in substantial removal of a surface portion of the body, yet which are sufficient to reduce both surface and bulk impurities. Typically, the body is treated with the plasma in the absence of simultaneous deposition of material onto the body. Advantageously, an isothermal, oxygen or oxygen-containing plasma is utilized. The invention is useful for reducing chlorine impurities by at least about 30% to a depth of at least about 10 .mu.m, with accompanying reduction of hydroxyl impurities. The invention thus provides a useful method for reducing the concentration of impurities that contribute to imperfections during the process of drawing fiber from an optical fiber preform, without requiring substantial removal of the surface of the preform.

摘要： This invention provides a method of increasing adhesion of radiation-cured, inner primary coatings on glass optical fibers. A glass optical fiber drawing tower has a controllable variable amperage electron beam for exposing different sections of a glass optical fiber with different amperage levels of electron beam radiation. The different sections of the glass optical fiber after being exposed to the selected amperage levels of electron beam radiation are then coated with an inner primary coating composition which is finally cured by exposure to actinic radiation. Later formed sections of the same glass optical fiber can be exposed to different amperage levels of electron beam radiation and then coated and cured. The different sections of the glass optical fiber which have been coated with an inner primary coating using this method demonstrate correspondingly different degrees of coating adhesion. Reduced levels of adhesion promoter are required for inner primary coating compositions when using this method.
