摘要：

Piezoelectric resonance contributions to the electrooptic coefficients in ferroelectric PZN-8PT single crystals were studied by a dynamic electrooptic measurement carried out using a continuous frequency scan over the range of frequency covering the sample's fundamental resonances. At certain frequencies relevant to piezoelectric resonance of a given mode, it is found that the E-field modulated optical transmission are greatly enhanced (> 2 orders of magnitude). Such enhancement is mode selective and scales with strain or the rate of change of dielectric permittivity. Instead of having linear dependence on the electric field, the piezoelectric resonance enhanced optical transmitted signal in this crystal shows a near linear response to the power of the modulating electric field.
