Abstract

Er3+-doping effect on electro-optic property of LiNbO3 crystal has been studied. A series of congruent LiNbO3 crystals homogenously doped with different Er3+ concentrations up to 2 mol% in melt were grown. Unclamped electro-optic coefficients r13 and r33 of these crystals were measured by Mach-Zehnder interferometry. The results show that both r13 and r33 reveal little dependence on Er3+ doping level. r13 hardly changes in the studied Er3+ doping level range 0-2 mol% within the experimental error of 3%. r33 reveals a degradation tendency with a rise in the Er3+ doping level, but the degradation is no more than 5% in the Er3+ doping level range studied. The small effect is consistent with previous result that the performance of an electro-optic device based on Ti4+-diffused Er3+-doped LiNbO3 waveguide is not influenced noticeably by Er3+-doping. A qualitative, comprehensible explanation is given for the small effect.
