    Abstract: A method for binding a first optical element to a substrate is disclosed. The method may include receiving a first optical element and a substrate. The method may include positioning an indium foil between the first optical element and the substrate. The method may include securing the first optical element to the substrate to produce a pre-bonded assembly, wherein the indium foil is disposed between the first optical element and the substrate. The method may include heating the pre-bonded assembly above a melting temperature of the indium foil. The method may include cooling the pre-bonded assembly. The method may include releasing the pre-bonded assembly, wherein releasing the pre-bonded assembly releases a bonded structure.

    Abstract: To overcome problems of fabricating conventional core-clad optical fibre from non-silica based (compound) glass, it is proposed to fabricate non-silica based (compound) glass optical fibre as holey fibre i.e. one contining Longitudinal holes in the cladding. This removes the conventional problems associated with mismatch of the physical properties of the core and clad compound glasses, since a holey fibre can be made of a single glass composition. With a holey fibre, it is not necessary to have different glasses for the core and cladding, since the necessary refractive index modulation between core and cladding is provided by the microstructure of the clad, i.e. its holes, rather than by a difference in materials properties between the clad and core glasses. Specifically, the conventional thermal mismatch problems between core and clad are circumvented. A variety of fibre types can be fabricated from non-silica based (compounds) glasses, for example: single-mode fibre; photonic band gap fibre; highly non-linear fibre; fibre with photosensitivity written gratings and other refractive index profile structures; and rare-earth doped fibres (e.g. Er, Nd, Pr) to provide gain media for fibre amplifiers and lasers.

    Abstract: PURPOSE:To reduce the scattering loss of infrared ray and to increase the strength of a fiber by forming a hollow thin pipe or fiber for clad connection from ionic crystal or metal, filling the pipe with ionic crystal molten substance as a core and cooling the moldings gradually to complete single-crystalization. CONSTITUTION:Ionic crystal 1 such as LiF and CaF is melted in a crucible 2 and the hollow cylindrical seed crystal of the ionic crystal whose size is made to consist with that of a concentric double pipe die 4 is put on the die 4, dipped in the molten ionic crystal through the die 4 and pulled out from the crucible 1 gradually to obtain a hollow fiber 5. A drum which the fiber 5 is wound around is installed inside of a large furnace 10, one end of the fiber 10 is dipped in ionic crystal molten substance 9, a core, and the other end is connected to a trap 8 to fill the fiber 5 with the molten substance with a vacuum pump 7. After cooling the fiber gradually and transferring it to another furnace, the fiber 5 is pulled out from the furnace gradually to get a single crystallized optical fiber while keeping the temperature just under the melting point of the crystal. When a metallic hollow pipe is used as a clad fiber, the process after the filling of core crystal molten substance is repeated in the same manner as mentioned above.
