  • Raman-active optical fiber
    Patent number: 7008892
    Abstract: An optical fiber has a fiber core with a higher refractive index and a cladding surrounding the core with a lower refractive index. The fiber core is made of a multi-component oxide glass composition which consists of a glass-forming component and two Raman-active components. The glass former is SiO2 and the Raman active components are of Li2O and Nb2O5. The concentration of the glass former is between 30 and 90 mol % and of the Raman active components is up to 50 mol % in total. The composition may further include a glass-modifying component of alkaline such as Li2O, Na2O, K2O, Rb2O, Cs2O or earth-alkaline such as BeO, MgO, CaO, SrO, BaO in a concentration of up to 40 mol %.
