UV generation in optical fibres has long been deemed challenging because of lack of suitable lasing ions in the UV and the poor transparency of germanosilicate fibres at wavelengths shorter than λ=400nm.
In our experiments, optical fibres with pure silica core and fluorosilicate cladding have been used, providing a loss smaller than 1dB/m at λ<300nm. Two different techniques were used to achieve light generation at λ<400nm: nonlinear optics in tapered optical fibres with sub-micrometric diameter (nanofibers) and doping with rare-earths.
