    Abstract: A method forms an optical fiber preform. The method includes forming a sol-gel-derived rod having a first diameter. Forming the sol-gel-derived rod includes preparing a sol-gel solution including at least 3 mole % of a catalyst. The sol-gel solution is allowed to undergo gelation to form a wet gel monolith. The wet gel monolith is dried and shrunk by exposing the wet gel monolith to a temporal temperature profile, thereby forming a xerogel monolith. The xerogel monolith is consolidated, thereby forming the sol-gel-derived rod. The method further includes drawing the sol-gel-derived rod to substantially reduce its diameter, thereby forming a drawn rod having a second diameter less than the first diameter.

    Abstract: A burner module for delivering a flow of chemical reactants to a combustion site of a chemical vapor deposition process includes a plurality of substantially planar layers. The substantially planar layers are arranged in a generally parallel and fixed relationship and define an inlet, an outlet and a passage fluidly connecting the inlet and outlet. At least one of the layers is a distribution layer having a plurality of apertures therethrough and fluidly communicating with the passage. The plurality of apertures collectively define a non-uniform pattern arranged and configured to improve the uniformity of a flow out through the outlet. Burner adapter and assembly embodiments are also included.

    Abstract: A dispersion control fiber and a method of manufacturing a large size preform. The dispersion control fiber comprises a core composed of SiO2, GeO2, and P2O5, and a cladding composed of SiO2, GeO2, P2O5, and Freon. The P2O5 content is selected not to exceed 10% of the total weight of a compound composing the core. The method of manufacturing a large size preform for a dispersion control fiber by an MCVD process comprising depositing SiO2, GeO2, P2O5, and Freon in an inner periphery of a deposition tube to form a cladding layer, and depositing SiO2, GeO2, and P2O5 on an inner periphery of the cladding layer to form a core layer.

    Abstract: The present invention provides an optical fiber for use in fiber lasers and amplifiers wherein the optical fiber has a core member surrounded by a cladding member for receiving pump energy and transferring the pump energy to the core member. The optical fiber also has an outer layer surrounding the cladding member. The cladding member has a circular exterior periphery and a predetermined refractive index (nc). The cladding member has an index modified region that directs light to the core member. The index modified region has a stress field portion with a predetermined refractive index (ns). The difference between the refractive index of the cladding member and that of the stress field portion (nc−ns) is within such a range that the stress field portion does not affect the polarization properties of the light traveling in the core member. Preferably, the difference between the refractive index of the cladding member and that of the stress field portion (nc−ns) is less than 10−4, and more preferably 10−5.
