Abstract
A folded electro-optic modulator is provided. The folded electro-optic modulator includes: a first main electrode, a first waveguide arm, a second main electrode, a second waveguide arm and a third main electrode arranged in sequence, and the following structures provided in each even-ordered radio-frequency modulation region of the folded electro-optic modulator: a plurality of first sub-electrodes; a plurality of second sub-electrodes; a plurality of third sub-electrodes; and a plurality of fourth sub-electrodes.
Claims10
A folded electro-optic modulator, comprising:
- a first waveguide arm and a second waveguide arm, which are in a folded form as a whole and do not intersect with each other;
- a first main electrode, a second main electrode and a third main electrode, wherein the first main electrode, the second main electrode and the third main electrode are in a folded form as a whole and do not intersect with each other, and the first waveguide arm is located between the first main electrode and the second main electrode, and the second waveguide arm is located between the second main electrode and the third main electrode, and the first main electrode and the third main electrode are ground electrodes for radio-frequency signals, and the second main electrode is a signal electrode for the radio-frequency signals;
- and
- the following structures provided in each even-ordered radio-frequency modulation region of the folded electro-optic modulator in a transmission direction of the first waveguide arm and the second waveguide arm;
- a plurality of first sub-electrodes, wherein each of the plurality of first sub-electrodes is connected to a side of the first main electrode close to the second main electrode by using a first connecting arm that is insulated from and intersects with the first waveguide arm;
- a plurality of second sub-electrodes, wherein each of the plurality of second sub-electrodes is connected to a side of the second main electrode close to the first main electrode by using a second connecting arm that is insulated from and intersects with the first waveguide arm;
- a plurality of third sub-electrodes, wherein each of the plurality of third sub-electrodes is connected to a side of the second main electrode close to the third main electrode by using a third connecting arm that is insulated from and intersects with the second waveguide arm;
- and
- a plurality of fourth sub-electrodes, wherein each of the plurality of fourth sub-electrodes is connected to a side of the third main electrode close to the second main electrode by using a fourth connecting arm that is insulated from and intersects with the second waveguide arm.
