Abstract:   (1048 Views)

In this research design and fabrication of an integrated electrooptical modulator in lithium niobate is presented. For fabrication of waveguides in this modulator the proton-exchanged method was used. In order to decrease the half wave voltage of the modulator, a common mask was used for fabrication of waveguide and electrodes that leads to decreasing of the distance between the electrodes. In addition, by using finite element method, influence of the shape of electrodes on the overlap coefficient of electric field and waveguide mode and the impedance of electrodes were calculated. At last impedance matching section was designed and fabricated for reduction of the required modulation voltage that leads to achieving half wave modulation voltage of 6 V.

Keywords: Light Modulator, Lithium Niobate, Waveguide, Proton Exchange, Half Wave Voltage
