摘　　要：通过对离子扩散机理和有源光波导重叠积分的分析 ,得知可以使用电场辅助离子交换技术制作有源光波导 ,实现波导对光场的更有效的限制 ,增大重叠积分因子 ,从而提高波导增益。In this paper the ion diffusion mechanism in the glass substrate and the overlap integral of active optical waveguide have been analysed. It’s known that the active optical waveguide which is fabricated by the field assisted ion-exchange technology can increase the mode confinement at both pump and signal wavelengths. So the overlap integral factor and the guide gain can be enlarged.
