Two-dimensional photonic crystals in lithium niobate (LiNbO3)

Abstract

We show the feasibility of two-dimensional structures air/LiNbO3 which ensures the achievement of ordered functions such as dynamic filtering. A study by FDTD (Finite Difference Time Domain) simulation shows that a variation of 0.005 of the refractive index in LiNbO3 allows a linear shifting of the Photonic Band Gap of 4.1 nm.
