【Abstract】 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.更多还原
