Abstract

The paper presents the results of a study of the influence of the geometric parameters of the mathematical model of a photonic-crystal (PhC) direct waveguide, based on thin-film lithium niobate on an insulator, on the optical insertion loss. Based on the obtained model of a direct photonic-crystal waveguide, a model of a photonic-crystal waveguide structure with a 60° bend was built, based on thin-film lithium niobate on an insulator, and the model parameters were optimized using the MMA method according to the principle of identifying the boundaries of air holes as a Bernstein polynomial 1 order followed by "stretching", which made it possible to reduce the insertion optical loss by a factor of 76 of a photoniccrystal waveguide structure with a 60° bend relative to a waveguide with a bend without optimizing the parameters.
