| Abstract: | A Mach-Zehnder interferometer optical modulator based on Lithium niobate （LiNb03, abbreviated as LN） photonic wires is obtained in this paper. Its structure size parameters and characterization are optimally de tromagnetic simulation software signed and analyzed respectively, b that based on the finite element me y using the commercial elec thod. Three main results are obtained. First, it has compact size. Second, a good linear relationship between the output light transmittance of the device and the in within a large scale. Third, it has sta put ble voltage applied on the interferometer arm is confirmed effect of the changes of the operating light wavelength upon the changes of transmittance of the output light. |
