Applicability of the Effective Index Method for the Simulation of X-Cut LiNbO<sub>3</sub> Waveguides

Applicability of the Effective Index Method for the Simulation of X-Cut LiNbO<sub>3</sub> Waveguides

Photonic integrated circuits (PIC) find applications in the fields of microwaves, telecoms and sensing. Generally, PICs are fabricated on a base of isotropic materials such as SOI, Si<sub>3</sub>N<sub>4</sub>, etc. However, for some applications, anisotropic substrates such a...
