In this paper design and fabrication of an integrated electrooptical modulator in lithium niobate by proton exchange process is presented. In order to decrease the drive voltage of the modulator, and to use a simpler manufacturing process without complicated alignment systems, a common aluminum mask was used for fabrication of waveguide and electrodes that leads to zero spacing between electrode and waveguides. Also to reach impedance matching between signal source and load a tapering section was designed and fabricated. In addition, for design of different parts of modulator, numerical and analytical methods was used to calculate proton diffusion, refractive index change of the waveguide, light mode profile in waveguide, electric field profile of the electrodes and length and characteristics of transmission line.
