    Abstract: In one aspect, a method is provided for molding from glass complex optical components such as lenses, microlens, arrays of microlenses, and gratings or surface-relief diffusers having fine or hyperfine microstructures suitable for optical or electro-optical applications. Thereby, molds are used, which define the profile of the optical components, made on metal alloys, particularly titanium or nickel alloys, or refractory compositions, with or without a non-reactive coating are provided. Given that molding optical components from oxide glasses has numerous drawbacks, it has been discovered in accordance with the invention that non-oxide glasses substantially eliminates these drawbacks. The non-oxide glasses, such as chalcogenide, chalcohalide, and halide glasses, may be used in the mold either in bulk, planar, or power forms. In the mold, the glass is heated to about 10-110°C, preferably about 50°C, above its transition temperature (Tg), at which temperature the glass has a viscosity that permits it to flow and conform exactly to the pattern of the mold.

    Abstract: The present invention relates to improved photonic crystal optical fibres that in preferred embodiments confine light to a core region of the fibre by the action of both a photonic band-gap cladding and an antiresonant core boundary, at the interface between the core and cladding. According to embodiments of the present invention, a fibre has a core (210), comprising an elongate region of relatively low refractive index, a photonic bandgap structure arranged to provide a photonic bandgap over a range of wavelengths of light including an operating wavelength of light, the structure, in a transverse cross section of the waveguide, surrounding the core and comprising elongate relatively low refractive index regions interspersed with elongate relatively high refractive index regions and a relatively high refractive index boundary at the interface between the core defect and the photonic bandgap structure, the boundary having a thickness that varies around the core to define features (265) that are substantially anti-resonant at the operating wavelength of the fibre.

    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 translation: 为了克服从非二氧化硅(复合)玻璃制造常规的包芯光纤的问题,提出了制造非二氧化硅基(复合)玻璃光纤作为多孔纤维,即在包层中连续的纵向孔。 这消除了与芯和包覆复合玻璃的物理性质失配相关的常规问题,因为多孔纤维可以由单一玻璃组合物制成。 使用多孔光纤,由于芯和包层之间必需的折射率调制由包层的微结构即其孔提供,而不是通过材料性质的差异来提供用于芯和包层的不同的玻璃。 在包层和核心眼镜之间。 具体来说,芯和包层之间常规的热失配问题被规避。 各种纤维类型可以由非二氧化硅(化合物)玻璃制成,例如:单模纤维; 光子带隙光纤; 高度非线性的纤维; 具有光敏写入光栅的纤维和其他折射率分布结构; 和稀土掺杂光纤(例如Er,Nd,Pr),为光纤放大器和激光器提供增益介质。

    Abstract: A vertically disposed apparatus used to make core-clad optical fibers includes an inner elongated cylinder removably closed at the top and provided at the bottom with an inner exit port of a smaller diameter than the inner cylinder and an outer cylinder, disposed around the inner cylinder, removably closed at the top and provided at the bottom with an outer exit port of a smaller diameter than the outer cylinder. The inner exit port is of a smaller diameter than the outer exit port and is disposed directly above the outer exit port. The apparatus also includes a heater for heating the inner and outer cylinders and access to the inner and the outer cylinders for individually pressurizing inner and outer cylinders. The process by which the core-clad optical fibers are made includes the steps of placing a solid glass core rod into the inner cylinder of the apparatus described above, placing a solid glass cladding tube into the outer cylinder, melting the core rod and the cladding tube, quickly cooling the molten core rod and cladding tube to the drawing temperature, individually pressurizing the molten core rod and cladding tube, and drawing the core-clad optical fiber through the exit ports.
