摘要：

The overlap integral describing the small signal gain coefficient in Er:Ti:LiNbO3 channel waveguides is numerically evaluated, and the results are used to discuss the polarization dependence and the influence of the erbium ion distribution. It is shown that bleaching is obtained at a substantially lower pump power for an extraordinarily polarized mode. We also study the influence of the overlap and the mode confinement at different pump bands, indicating that the poorer overlap between the pump and signal mode at shorter pump wavelengths can be compensated for by an improved overlap with the erbium ions.
