摘要
基于内插隔离－耦合环两段级联新结构，采用９８０ｎｍ与１４８０ｎｍ激光二极管混合泵浦方式，研制出在１．５５μｍ波段兼具高增益（４２．８ｄＢ）、大功率（１５．２ｄＢｍ）、低噪声系数（４．
Based on two stage erbium fiber and optical loop couping configuration, 980 nm and 1480 nm LD pumped erbium doped fiber amplifier (EDFA) has been developed. The characteristics of EDFA have investigated experimentally at wavelength of 1553 nm. Results show that the small signal gain, noise figure and maximum output power are of 42.8 dB, 4.4 dB and 15.2 dBm, respectively.
