Paper Abstract

In this research, silica based planar waveguide and powdered glasses doped with Er2O3, Yb2O3, TiO2 and Al2O3 have been fabricated by sol-gel process. The photoluminescence enhancement has been demonstrated to be seven and four times that without Yb co-doping when pumped by a 980 nm laser diode and a 488 nm Ar+ laser respectively. The strongest fluorescence is observed form the 93 SiO2: 7 TiO2: 10 AlO1.5: 1 YbO1.5 glass. Dependence of the photoluminescence intensity and lifetime on Er3+ as well as Yb3+ concentration has been experimentally studied.
