Abstract: The fibre comprises a core (2) having an index N and diameter of 10 μm or more, surrounded by a ring (4) having an index N+Δn and thickness ΔR, and cladding (6) surrounding the ring and comprising for example air gaps (8). According to the invention: Δn≧10−3 and ΔR=α/(Δn)β [1] where: 5×10−4 μm≦α≦5×10−2 μm and 0.5≦β≦1.5. The numbers α and β are dependent on the wavelength λ of the light guided by the fibre, the number of missing gaps therein, the diameter d of the gaps, the spacing Λ thereof and N. To design the fibre, λ, the number of missing gaps, d/Λ, the core doping content, Λ0 and Δn are chosen; and ΔR is determined using equation [1] so as to obtain a flattened fundamental mode.

In one embodiment, the method also includes filtering the aerosol so as to remove aerosol particles outside of a particular range of sizes. Also described is a unique aerosol generator that is particularly useful in generating aerosols of rare-earth dopants.

Abstract: The invention starts from a known component of quartz glass for use in semiconductor manufacture, which component at least in a near-surface region shows a co-doping of a first dopant and of a second oxidic dopant, said second dopant containing one or more rare-earth metals in a concentration of 0.1-3% by wt. each (based on the total mass of SiO2 and dopant). Starting from this, to provide a quartz glass component for use in semiconductor manufacture in an environment with etching action, which component is distinguished by both high purity and high resistance to dry etching and avoids known drawbacks caused by co-doping with aluminum oxide, it is suggested according to the invention that the first dopant should be nitrogen and that the mean content of metastable hydroxyl groups of the quartz glass is less than 30 wtppm.
