Paper Abstract

The study reveals an innovative design of the optical waveguide based on potassium tantalate niobate (KTN) crystal. The device’s guiding properties, which benefits from the large electro-optic coefficients of KTN crystal, can be dynamically controlled by an external electric field in a relatively simple waveguide structure. Finite Element Method (FEM) and Beam Propagation Method (FEM) are used in the theoretical part of this work which shows that the KTN based dynamic waveguide has good potential on applications of several kinds of optical switches and modulators.
