A holographic method for the determination of all linear electrooptic coefficients applied to Ce-doped strontium-barium-niobate
Using c- and a-cut plates of strontium-barium-niobate doped with 0.66 mol.% cerium all nonzero components of the linear electrooptic tensor r13, r42, r33 including the sign are determined from angular dependence of the two-beam coupling coefficient Γ using transmission and reflection geometry of holographic recording. We found: r13=56 pm/V, r42=38 pm/V, and r33=333 pm/V. In addition we calculated the effective trap density Neff to be 2.2×1017 cm-3. The advantages of this method as well as the values obtained are discussed.
