| 摘 要： | 在忽略放大自发辐射(ASE)及均匀掺杂和稳态的情况下,在初始能量转移效率的基础上从速率方程和传输方程出发,推导出了用于分析铒镱共掺波导放大器(EYCDWA)的新公式.利用这些公式分析了泵浦光功率、信号光功率、掺杂浓度、波导长度对放大器增益特性的影响,并与单掺铒波导放大器(EDWA)进行了比较,得到了一些具有实用价值的模拟结果.

| Abstract: | Novel formulas to analyze the gain characteristics of Er3+/Yb3+ co-doped waveguide amplifiers (EYCDWA) are derived from the rate equations and the light propagation equations under the uniform dopant and steady-state conditions,neglecting the amplified spontaneous emission and introducing initial energy transfer efficiency.Using these formulas,the effects of the pumping power,signal power,dopant concentration,and waveguide length on the gain characteristics of the EYCDWA are analyzed.A comparison is performed between the EYCDWA and the singly erbium-doped optical waveguide amplifier and some useful results are obtained. |
