摘要
采用两段级联掺铒光纤、980 nm和1480 nm LD混合泵浦方式,实验分析比较了内插光隔离器和内插光隔离-耦合环光路结构掺铒光纤放大器(EDFA)的增益、噪声系数和输出功率特性。研制出内插光隔离-耦合环的EDFA,在信号波长1553.5 nm处,小信号增益为42.8 dB,噪声系数为4.4 dB,输出功率为15.2 dBm。
Abstract
Based on a two stage fiber, Erbium doped fiber amplifiers (EDFAs) pumped by 980 nm and 1480 nm laser diodes (LD) are investigated. Experimental comparisons of gain, noise figure and output power between the intermediate isolator configuration and the loop coupling configuration are discussed. A small signal gain of 42.8 dB of EDFA has been obtained for the loop coupling configuration. The minimum noise figure and maximum output power at wavelength of 1553.5 nm are 4.4 dB and 15.2 dBm, respectively.
