Reduction of electro-optic half-wave voltage of 0.93Pb(Zn1/3Nb2/3)O3-0.07PbTiO3 single crystal through large piezoelectric strain

► We have made detailed analysis on the the influence of converse piezoelectric effect on the electro-optic coefficient of single domain relaxor-based 0.93Pb(Zn1/3Nb2/3)O3-0.07PbTiO3 (PZN-0.07PT). ► We showed that Vπ13T can be reduced by a factor of 8 and Vπ13T can be decreased by more than an order of magnitude due to the large piezoelectric effect of PZN-0.07PT. ► The dimension of optic phase modulators made of PZN-xPT single can be reduced by a factor of 5 compared to those made of LiNbO3 and BaTiO3 single crystals.
