Polarization properties of PLZT under an applied voltage by the Mueller matrix (3rd report)

Comparison between PLZT and LiNbO₃

Abstract

Ferroelectric ceramics has distributions of spontaneous polarizations caused by crystal grains and domains. Therefore, a transmitted light is depolarized and it is difficult to obtain detailed polarization properties of a ceramic. For measurement of total polarization properties quantitatively, we focused on the Mueller matrix describing all polarization properties including depolarization. For analysis of the influence of crystal grains on polarization properties, we have evaluated dependency of polarization properties of polycrystal of PLZT and single crystal of LiNbO₃ on the applied voltages.
