Abstract(in English) | We propose an optical modulator which is composed of thin disk pillbox-type resonators, coupling waveguides, and electrodes. Considering proton exchanged LiNbO_3 as a material, frequency characterisitcs of a pillbox-type optical modulator is numerically analyzed with scattering matrices. Amplitude-expanded pulse generation for modulation signals, such as sinusoidal wave and triangle pulse, is numerically calculated by changing modulation frequency. As a result, the mechanism of the amplitude-expanded pulse generation is clarified, and it is found that the amplitude of output pulse in theory is 9 times as large as the one of CW input. |
