Abstract

Silica based multi-component glass fibers were fabricated using core glass doped with erbium concentration in the range of 650 to 34000wtppm. The highest gain of 18dB was achieved at the Er3+ concentraion of 7000wtppm under pump wavelength and power of 1.48μm and 40mW, respectively. The gain decreased at concentration over 7000wtppm due to clustering of Er3+ ions. The increases in the threshold value of the pump power caused by clustering of Er3+ ions was also recognized.
