Abstract

In this study, we quantitatively simulate the thermal effect in the application of high-speed KTN beam deflectors. Dielectric heating can contribute to a substantial temperature increase in high-speed continuous KTN electro-optic (EO) beam deflection. The influence of dielectric heating in KTN is analyzed for different parameters, such as the beam deflection angle, geometric dimension, and the scanning frequency. The optimal structure that can minimize the thermal effect is explored.
