Abstract

The electric field or stress applied to a solid material can change its polarization or dimensions, thereby altering its properties and causing a piezoelectric effect. This effect can positively or negatively impact your material depending on the sought after application. In this paper, we present a quantitative COMSOL simulation on the influence of the piezoelectric effect on the performance of high speed KTN deflectors. This includes examining the following aspects: piezoelectric induced mechanical stress and refractive index modulation. Furthermore, methods of minimizing the negative impact of piezoelectric effect, such as soft clamping, are explored in order to optimize the performance of electro-optical deflectors.
