Abstract

Optical frequency comb plays an important role in the field of ultrafine optical signal detection and microwave photon signal processing, Lithium Niobate (LN) has high nonlinear coefficient and excellent electro-optical characteristics, the electro-optical modulator based on lithium niobate thin film has the advantages of low power consumption and high integration. In this paper, a cascaded intensity and phase modulator based on lithium niobate thin film is designed. The scheme of cascaded intensity modulation and phase modulator generating optical frequency comb is verified by simulation, and minimum bending radius of the thin film modulator is optimized by parametric scanning by finite element method to determine the optical mode limitation in the ridged waveguide. In order to further reduce the half-wave voltage of coplanar waveguide electrodes, a multi-variable constraint algorithm is used to co-simulate the relationship between overlapping integral and half-wave voltage by optimizing the thickness of buffer layer between electrodes.
