  • ELECTRO-OPTICAL MODULATOR, OPTICAL MODULATION SYSTEM, AND INTEGRATED OPTICAL CHIP
    Publication number: 20240142810
    Abstract: An example electro-optical modulator includes an electrode conversion portion and an optical modulation portion. The electrode conversion portion includes a first input electrode and a second input electrode, where the first input electrode is configured to receive a first modulation signal, and the second input electrode is configured to receive a second modulation signal. The optical modulation portion includes a first modulation electrode, a second modulation electrode, a third modulation electrode, a first modulation arm, and a second modulation arm. The first modulation arm is between the first modulation electrode and the second modulation electrode, and the second modulation arm is between the first modulation electrode and the third modulation electrode. The first modulation electrode is coupled to the first input electrode, and the second modulation electrode and the third modulation electrode are separately coupled to the second input electrode.
