Abstract
A LiNbO3 electrooptic grating modulator, which has good wavelength selection and high speed characteristics, is composed of coplanar microstrip electrodes with periodic small fins, a thin SiO2 buffer layer, and airbridge structure. The refractive index distribution in the modulator is analyzed by considering the linear electrooptic effects. The microwave characteristics are determined using 3D finite difference method (3D-FDM). Numerical simulations indicate that the airbridge structure have good speeding wave up effect. The modulator has quite good selecting wavelength modulation characteristics.
