Abstract: An electro-optic modulator includes an input waveguide, a beam splitter connected to the input waveguide, a modulation arm that is disposed on each branch of the beam splitter and modulates a signal. Each modulation arm is correspondingly disposed with a first layer electrode and a second layer electrode. The first layer electrode is a high-frequency traveling wave electrode and is configured to change carrier concentration in the modulation arm, the second layer electrode is a direct current electrode having an inductor function, and an inductor formed in the second layer electrode is connected to the first layer electrode. The electro-optic modulator has functions of a bias tee, so that integration of the electro-optic modulator can be improved without affecting its performance. High-density packaging layout difficulty and cabling pressure can be effectively reduced, and cabling and packaging of a multi-channel high-speed signal on a base board can be implemented.

Abstract: A Mach-Zehnder (MZ) modulator includes a splitter, two modulation arms, and a coupler. The two modulation arms include two optical transmission waveguides and two electrodes. The splitter is configured to perform power splitting on an optical carrier to obtain two optical carriers and input the two optical carriers to corresponding input ports of the two optical transmission waveguides, respectively. The two electrodes include a first electrode and a second electrode which are respectively configured to receive two differential electrical signals and apply the two differential electrical signals to the two optical transmission waveguides to change phases of the two optical carriers. Two input ends of the coupler are connected to output ports of the two optical transmission waveguides, respectively, and are configured to perform interference on the optical carriers whose phases are changed via the two modulation arms and output the optical carriers.
