摘要： The present invention relates in general to coupling of light from one or more input waveguides to an output waveguide or output section of a waveguide having other physical dimensions and/or optical properties than the input waveguide or waveguides. The invention relates to an optical component in the form of a photonic crystal fibre for coupling light from one component/system with a given numerical aperture to another component/system with another numerical aperture. The invention further relates to methods of producing the optical component, and articles comprising the optical component, and to the use of the optical component. The invention further relates to an optical component comprising a bundle of input fibres that are tapered and fused together to form an input coupler e.g. for coupling light from several light sources into a single waveguide. The invention still further relates to the control of the spatial extension of a guided mode (e.g. a mode-field diameter) of an optical beam in an optical fibre. The invention relates to a tapered longitudinally extending optical waveguide having a relatively larger crosssection that over a certain longitudinal distance is tapered down to a relatively smaller cross section wherein the spatial extent of the guided mode is substantially constant or expanding from the relatively larger to the relatively smaller waveguide cross section. The invention may e.g. be useful in applications such as fibre lasers or amplifiers, where light must be coupled efficiently from pump sources to a double clad fibre.

摘要： A microstructured fibre having a cladding comprising a number of elongated features that are arranged to provide concentric circular or polygonial regions surrounding the fibre core. The cladding comprises a plurality of concentric cladding regions, at least some of which comprising cladding features. Cladding regions comprising cladding features of a relatively low index type are arranged alternatingly with cladding regions of a relatively high index type. The cladding features are arranged in a non-periodic manner when viewed in a cross section of the fibre. The cladding enables waveguidance by photonic bandgap effects in the fibre core. An optical fibre of this type may be used for light guidance in hollow core fibres for high power transmission. The special cladding structure may also provide strong positive or negative dispersion of light guided through the fibre - making the fibre useful for telecommunication applications.

摘要： The invention relates to optical fibers for use in optical amplification of light, such as in optical fiber amplifiers and lasers and for use in delivery of high power light, in particular to a scheme for reducing amplified spontaneous emission at undesired wavelengths. The invention further relates to articles, methods and use. An object of the invention is achieved by a micro- structured optical fiber, which is adapted to guide light by the photonic bandgap effect and to have one or more pass bands and at least one stop- band over a wavelength range from λ stop1 to λ stop2- In an aspect of the invention, the at least one stop-band provides filter functions that suppress nonlinear effects. In another aspect, the core region is actively doped, and the active material has an emission spectrum with a higher value of the emission cross section σ E at a wavelength λ ASE between λ stop1 and λ stop2 than outside said wavelength range such that amplified spontaneous emission and lasing within the wavelength range from λ stop1 to λ stop2 is reduced. In still another aspect, the optical fiber exhibits photonic bandgaps at different wavelength ranges in different radial directions of a cross section of the optical fiber.

摘要： An object of the present invention is to provide new designs of microstructured optical fibres that may be fabricated without use of voids, such as fibres being realized using silica and silica doping techniques. The invention relates to a microstructured optical fibre that guides light in a core region (52), where the fibre has a cladding region that comprises a background material (51) and a number of cladding features or elements (50) that are elongated in the longitudinal direction of the fibre and have a higher refractive index than the cladding background material. The core region has a lower effective refractive index than the cladding, and the fibre may guide light in the core by photonic bandgap effects. The present invention provides designs of photonic bandgap fibres that may operate without the use of voids in the cladding, thereby simplifying fabrication of photonic bandgap fibres compared to prior art. The invention further provides photonic bandgap fibers with tuneable waveguiding properties, such as tuneable polarization. The invention further relates to a number of specific fibre designs that provide improvements with respect to dispersion characteristics, mode field diameters, propagation losses, polarization mode dispersion and other issues of relevance to optical communication systems.
