Electro-optic properties of potassium sodium strontium barium niobate ferroelectric thin films
|
Abstract:
Fully occupied ferroelectric ((KxNa1-x)0.4(SryBa1-y)0.8, 0.5051 of KNSBN films can be greatly improved by introducing alkali metal ions, the measured values of transverse electro-optic coefficient r51 of K0.2Na0.2Sr0.24Ba0.56Nb2O6, K0.2Na0.2Sr0.6Ba0.2Nb2O6, K0.2Na0.2Sr0.72Ba0.08Nb2O6 are 108.52pm/V, 119.98pm/V, and 126.96pm/V, respectively. An enhancement of r51 with Sr2+content in KNSBN films has been demonstrated.
