  • Optical modulator and control method therefor
    Patent number: 12372848
    Abstract: Disclosed are an optical modulator and control method therefor, the optical modulator includes an input waveguide, an adjustable ring-shaped resonant cavity, a feedback loop waveguide, a first mode converter, and an output waveguide. The input waveguide is configured to receive an initial optical signal, the adjustable ring-shaped resonant cavity is configured to perform resonance and modulation processing on the initial optical signal and output a first optical signal, the feedback loop waveguide is configured to receive and transmit the first optical signal, the first mode converter is configured to perform mode conversion processing on the first optical signal and output a second optical signal to the adjustable ring-shaped resonant cavity, the adjustable ring-shaped resonant cavity is further configured to perform resonance and modulation processing on the second optical signal and output a third optical signal, and the output waveguide configured to receive and output the third optical signal.
