    Abstract: A method that provides a new way to embed rare earth fluorides into silicate (or germania-doped silica) glasses by means of solution chemistry. Embedding rare earth fluorides into a silicate (or germania-doped silica) glass comprises the following steps. First, form a porous silicate core preform. Second, submerge the preform into an aqueous solution of rare earth ions. Third, remove the preform from the solution and wash the outside surfaces of the preform. Fourth, submerge the preform into an aqueous solution of a fluorinating agent to precipitate rare earth trifluorides from the solution and deposit in the pores or on the wall of the preform. This is followed by drying.

    Abstract: A method for fabricating an optical waveguide, comprising the following steps. That is, forming an optical waveguide on surface of a substrate via an atmospheric pressure chemical vapor deposition (AP-CVD) method using a silica raw material containing an organic material, and irradiating ultraviolet light on at least a portion of that optical waveguide. The refractive index of the portion of the optical waveguide irradiated with ultraviolet light increases. Since changing the refractive index in this way enables the formation of a diffraction grating, it is possible to manufacture optical filters and wavelength dispersion devices.

    Abstract: The present invention is directed at a method and device for manufacturing a preform. The method involves arranging a starting body within a channel as defined by a vessel. Then, the channel is supplied with a reactive gas containing a coating material precursor. A resonator then generates a plasma zone within the channel. The starting body is aligned in the channel such that the plasma zone concentrically surrounds the starting body. The axial movement of the resonator relative to the starting body is controlled such that a desired layer of coating material precursor reactively deposits on the starting body to form the preform. The method suppresses deposition on the inside of the vessel via suppressing means, which may involve inducing nodes in the E-field at the vessel walls, or using an suppressing gas on the inner surface of the vessel, or a combination of the two. The present invention is also directed at a device to facilitate the aforementioned method.
