Abstract
We report here the experimental results of pump-induced thermal effect in Er/Yb fibers. A 10-mm long fiber Bragg grating, written directly in a highly photosensitive B/Ge/Si annulus of a 12-mm long Er/Yb-P/Al/Si fiber, was employed for determining the temperature rise caused by nonradiative transitions in the Er/Yb fiber by measuring its Bragg wavelength shift. A temperature rise of 0.85 °C per mW of pump power was measured for the Er/Yb fiber. A fiber laser constructed with a FBG written directly in one end of the fiber and a mirror butt joined to the other end was investigated for the pump-induced thermal effect. Its lasing wavelength was shifted by 0.25 nm when the pump power was varying from 4 mW to 56 mW.
