| Abstract: | The far IR spectra and the photoconductivity of the proton-exchange LiNbO3 waveguide were measured. Experimental results show that the machanism of good photorefractive damage resistance of protonexchange LiNbO3 waveguide is related to the fact that its photoconductivity is 5-10 times higher than that of pure LiNbO3 crystal. |
