Nonlinear optical properties of calcium barium niobate epitaxial thin films.

We investigate the potential of epitaxial calcium barium niobate (CBN) thin film
grown by pulsed laser deposition for optical frequency conversion. Using second
harmonic generation (SHG), we analyze the polarization response of the generated
signal to determine the ratios d15 / d32 and d33
/ d32 of the three independent components of the second-order
nonlinear susceptibility tensor in CBN thin film. In addition, a detailed
comparison to the signal intensity obtained in a y-cut quartz allows us to
measure the absolute value of these components in CBN thin film: d15 =
5 ± 2 pm / V, d32 = 3.1 ± 0.6 pm / V and d33 = 9 ± 2 pm /
V.
