Abstract: An optical fibre for use in fibre lasers has the lasing additive eg Er.sup.3+, concentrated in center of the core. Preferably the core has an inner region which contains the additive and an outer region which is dopant free. The concentration of the dopant reduces the pump threshold for a laser and improves the gain performance for a given pump power. The fibre is conveniently made in MCVD. The use of Al.sub.2 O.sub.3 in the inner zone appears to reduce loss of dopant during tube collapse.

Abstract: A method of incorporating an additive or dopant oxide in a glass body produced by the flame hydrolysis technique. Particles of the primary glass former are produced by flame hydrolysis and deposited to form a porous body which is impregnated, in part at least, with a dopant which may be dissolved or suspended in a vehicle. The body is then thermally consolidated with the dopant dispersed therein.

Abstract: The present invention provides a process for fabrication of ytterbium (Yb) doped optical fiber through vapor phase doping technique. The method comprises deposition of Al2O3 and Yb2O3 in vapor phase simultaneously in combination with silica during formation of sintered core layer. This is followed by collapsing at a high temperature in stepwise manner to produce the preform and drawing of fibers of appropriate dimension. The process parameters have been optimized in such a way that Al and Yb-chelate compounds can be transported to the reaction zone without decomposition and condensation of precursor materials. Thus variations of dopants concentration along the length of the preform have been minimized to

Abstract: The fiber 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 fiber, the number of missing gaps therein, the diameter d of the gaps, the spacing Λ thereof and N. To design the fiber, λ, the number of missing gaps, d/Λ, the core doping content, Λ and Δn are chosen; and ΔR is determined using equation [1] so as to obtain a flattened fundamental mode.
