| Research Abstract |
To improve the precision of the components of third-order nonlinear optical susceptibility tensor, a measurement system has been developed using a polarized single beam combined with Z-scan method. The polarization of the beam is continuously varied from a linearly polarized one to a circularly polarized one through a elliptically polarized one. The values of the third-order susceptibility tensor have been measured on InP (001), (110), and (001) plane. The values have been analyzed using my expression derived from my light-propagating model of Gaussian beam with two-photon absorption. The measured polarization results have shown the good agreement the calculated those based on the values of the tensor components obtained in this study.
