掺铒铌酸锂波导放大器增益特性的理论分析

Theoretical analysis of gain of Er 3+ doped LiNbO 3 waveguide amplifier

对掺铒铌酸锂（Ｅｒ３＋：ＬｉＮｂＯ３）波导放大器在１４８０ｎｍ泵浦光单向和双向泵浦下的增益特性作了计算机模拟理论分析，采用二能级速率方程，忽略ＥＳＡ的影响，应用数值法得出方程解。

The characterizes of gain of Er 3+ :LiNbO 3 waveguide amplifier are studied. LiNbO 3 passive waveguide devices are small signal pump light establish on a modeling of quasi two level system built specially for pump wavelength at 980nm and neglecting ESA and ASE. The numerical simulation is done for single and double pass configuration respectively.
