Popis: For the first time the reduced-pressure plasma CVD technology was applied to fabrication of active silica optical fibers with all-depressed index structure. Using surface plasma CVD method, fiber preforms with an Er-doped silica core and fluorine doped silica cladding have been prepared and tested. A possibility of high performance active fiber fabrication using the SPCVD has been demonstrated. An influence of fluorine co-doping on luminescence features of Er 3+ ions in a silica host has been examined. The erbium concentration-associated clustering effects in pure silica host synthesized by the SPCVD were compared with those in germanosilicate host synthesized by the MCVD.
