AbstractFerroelectric oxide thin films show considerable potential as electro-optic and non-linear optical materials. Of particular interest are the niobates such as strontium barium niobate and potassium niobate. The growth of these epitaxial oxide films by metal-organic chemical vapor deposition (MOCVD) has been investigated. This technique has yielded epitaxial thin films with excellent non-linear optical properties. Issues concerning the epitaxy of these thin films and its relationship to their optical and nonlinear optical properties are discussed.

A supra-molecular crystal, 1-[C6H13NH][18-crown-6][ClO4] monohydrate, has been reported to show reversible dielectric anomalies and nonlinear optical properties, which suggests that it could be conceived as the potential switchable dielectric and non-linear optical material.

The third-order nonlinear optical properties of the N-6-hydroxy-hexyl-4-azophenyl-carbazol have been investigated both theoretically and experimentally. Using Z-scan method with a femtosecond laser (440[Formula: see text]nm, 190[Formula: see text]fs), the third-order nonlinear optical properties of the N-6-hydroxy-hexyl-4-azophenyl-carbazol were determined. The second-order hyperpolarizability [Formula: see text] of the experiment result was found to be [Formula: see text][Formula: see text]esu. We have also calculated the second-order hyperpolarizability based on the sum-over-states (SOS) method. The theoretical value was in accord with the experiment result. The result showed that the N-6-hydroxy-hexyl-4-azophenyl-carbazol was one of the promising third-order nonlinear optical materials.

We have investigated the third order nonlinear optical properties of pyrrole Schiff bases synthesized by condensing pyrrole-2-carboxaldehyde with two different diamines. The nonlinear optical measurements were performed using the nano- second laser pulses at 532nm wavelengthby employing the Z-scan technique. The Z- scan spectra reveal a large negative non-linear refraction co-efficient .The nonlinear refractive index was found to be of the order of 10-14cm2/W and the magnitude of third order susceptibility was of the order of 10-13esu. These compounds exhibit good optical power limiting property under nano-second regime and TPA (Two Photon Absorption) is the dominating process leading to the non-linear behavior.
