In the recent past we have studied the granulated silica method as a versatile and cost effective way of fiber preform production. We have used the sol-gel technology combined with a laser-assisted remelting step to produce high homogeneity Rare Eart

We demonstrate a multicore multidopant fiber which, when pumped with a single pump source around approximately 800 nm, emits a more than one octave-spanning fluorescence spectrum ranging from 925 to 2300 nm. The fiber preform is manufactured from gra

Two techniques for manufacturing fiber performs- silica powder sol-gel processing and MCVD are compared. Preforms with core material doped with Nd3+ and Yb3+ are produced with both methods and are characterised with respect to spectral characteristic

A new fabrication process of active optical silica glass based on direct sand vitrification is proposed. This method, an alternative to chemical vapor deposition (CVD), allows the fabrication of homogeneous and highly Yb(3+)-doped rods that are ten t

We demonstrate a single-core multiply doped fiber that, when pumped with a single pump source of approximately 800 nm, emits a more than two-octaves-spanning fluorescence spectrum ranging from 365 to 2300 nm. The fiber preform is manufactured from gr

Mean index changes >10-3 were obtained in non-hydrogen-loaded 3% GeO2-doped silica fibers with a 9/40 micrometer core/cladding diameter using a cw 244-nm-Ar+-laser. Core stress changes are positive indicating a compaction contribution to the index ch
