In an aspect of this embodiment, the amount of RE2F6 is selected according to the formula: RE2F6 = (K)(R/r) (Al2O3 + Ga2O3 - R2O) 2, where R is one of Na, K, Rb and Cs; 0.7 ; and r is the radius of RE . A method for making the new material is also disclosed and includes preparing an oxyfluoride glass containing rare earth ions by a conventional melting method and subjecting the glass to a heat treatment (ceramming), thereby precipitating preferentially fluoride fine crystals containing a large amount of rare earth ions.

Abstract: An optical fiber preform is made by supplying the base glass reactant and the dopant glass reactant to a burner that generates a flame in which a stream of glass particles is produced. The burner moves with respect to a rotating mandrel to deposit layers of glass particles on the mandrel. During the deposition of a portion of the preform, the flow rate of the dopant glass reactant is varied in accordance with a first recipe of dopant flow as a function of burner position as the burner moves longitudinally along the substrate to form one of the layers. The flow rate of the dopant glass reactant varies in accordance with a second recipe of dopant flow as a function of burner position as the burner moves longitudinally along the substrate to form a layer adjacent to the one layer. The second recipe is different from the first recipe, and the flow rate of the dopant glass reactant changes during the step of moving the reaction zone to form the one layer. The methods disclosed particularly relate to the production of preforms of constant diameter for dispersion decreasing fibres.

Abstract: A variable period amplitude grating mask (10) for use in making a long period Bragg grating is realized by a helically coiled spring (14). Stretching or compressing the spring changes the periodicity of the mask (10). A photosensitive optical waveguide (100), planar or fiber, is positioned within the spring coils (16) along the major axis of the spring (14). Actinic radiation is incident on the masked waveguide, and induces an index of perturbation in the waveguide having the periodicity of the mask. Different spring coil sizes and/or orientation of the waveguide respect to the mask provide linear or nonlinear (chirped) grating periods.

Abstract: A compact monolithic interferometric switch as a Mach-Zehnder switch is formed such that one of the waveguide paths (47) between the input and output couplers contains a material which exhibits a resonant nonlinearity, whereby its refractive index changes when pump power propagates through it. Each of the waveguide paths (47, 46) has a different propagation constant whereby signal light is subject to a different delay in each path when no pump power is propagating through the rare nonlinear path. An input signal applied to the input of the switch appears at a first output terminal when the pump power does not propagate through the nonlinear path, it appears at a second output terminal when the pump power is applied to the nonlinear path. Switching occurs at relatively low levels of pump power.

Abstract: An optical fiber ribbon includes a plurality of coated, substantially coplanar optical fibers (2) and a ribbon matrix material (4) which maintains the pluratily of coated optical fibers (2) in substantially coplanar alignment. Each of the optical fibers (2) includes a glass core (6), a cladding layer (8) surrounding and adjacent to the glass core (6), and a primary polymeric coating material (10), preferably containing a silicone, surrrounding and adjacent to the cladding layer (8). The primary polymeric coating material (10) adheres to the cladding layer (8) to form a cladding layer-primary polymeric coating interface. Upon application of a longitudinal stripping force at the cladding layer-primary polymeric coating interface, the ribbon matrix material (4) and the primary polymeric coating material (10) are substantially removed from the cladding layer (8).
