| 摘 要： | 推导出了ＥＤＦＡ的ＡＳＥ功率与信号光功率的关系式。当ＥＤＦＡ作为功率放大器时，由于对ＥＤＦＡ的光功率速率方程数值求解能够求得信号光功率在掺铒光纤纵向的分布，用该方法能够简便地计算出ＥＤＦＡＡＳＥ光输出功率。

| Abstract: | Spontaneous emission in EDFAs is amplified with signal , constructing amplified spontane- ous emission . In order to analyze the noise characteristics of EDFAs , the output power of ASE must be cal- culated . In this paper , the relation equations between ASE and signal optical power are derived . When EDFA is used as the power booster , the ASE output power of EDFAs can be calculated simply by this method because the longitudinal distribution of signal optical power in EDFA can be calculated by numer- ical solution of the optical power rate equations of EDFA . |
