    摘要: The present invention relates to amorphous thin films and methods of manufacturing the same. These amorphous thin films contain zirconium oxide (ZrO2), preferably at a concentration of at least 30 mol %, and other metal oxides and have surprisingly good mechanical and optical properties. In some embodiments of the present invention, the thin films may be further processed to obtain fluorinated glasses containing the same metal elements as the metal oxides.

    摘要: To provide a process for producing an air cladding type optical fiber by a method other than extrusion molding.A process for producing an optical fiber comprising a hollow glass fiber with an optical transmission glass held to extend in its axial direction at its center, which process comprises a step of heating and drawing a glass rod having three or more holes with an equal diameter provided around its center axis to extend in its axial direction where the distance between each hole and the axis is mutually equal and the distance between adjacent holes is mutually equal, and a portion surrounded by such holes will constitute said optical transmission glass, while applying pressure to expand the holes with one end of the rod closed, to form a preform wherein glass between the holes is in a plate form, and subjecting the preform to wire drawing to form an optical fiber in which said optical transmission glass is held by plate glass.

    摘要: A method of molding low-temperature glass into a preform for formation by drawing into glass fiber, especially for transmission of mid-IR, involves casting a cladding glass into a mold cavity in the shape of the desired preform to form a cladding layer, and forming a glass core within the cladding layer, wherein the molten cladding glass is drained from the bottom of the mold cavity, forming an annular coating of cladding glass as an annular layer, and the core glass is quickly added within the annular cladding layer to form the glass core with the cladding layer thereabout.

    摘要: A germanate glass composition suitable for use in a fiber amplifier for broadband amplification of optical signals is provided. The glass preferably includes 35-75% GeO2, 0-45% PbO, 5-20% BaO, 5-20% ZnO, and 2-10% R2O (R=Na, Li, K). It is doped with thulium ions (Tm3+) and codoped with holmium ions (Ho3+). The glass composition of the invention results in a remarkably large bandwidth as compared with previous glasses. It is also highly compatible with existing silica optical fibers.
