Abstract

Gain characteristics of Er3+ -doped fibers for different pump wavelengths between 1.455 and 1.510 μm are investigated to obtain the optimum pump wavelength. It is found that the efficient pump wavelengths are located in the 1.460-1.475 μm range for Er3+ -doped Al2O 3-GeO2-SiO2 and Er3+ -doped GeO 2-SiO2 fibers, where a maximum gain of about 27 dB was obtained with an absorbed pump power of 31 mW.
