Abstract: An optoelectrical assembly includes a voltage conversion circuit, an optoelectrical semiconductor device, an optoelectrical detection circuit, and a controller. The voltage conversion circuit provides a bias voltage to the optoelectrical semiconductor device, and adjusts, by changing the bias voltage, an output optical power. A differential resistance value (Rdiff) of the optoelectrical semiconductor device within a range of a target optical power satisfies 0.1 ohm (Ω)≤Rdiff≤50Ω, and the differential resistance value is a ratio of a voltage variation to a current variation corresponding to the voltage variation. The optoelectrical detection circuit detects the output optical power, and outputs a detection signal to the controller. The controller determines a control signal based on the detection signal, and outputs the control signal to the voltage conversion circuit, where the control signal is used to adjust the bias voltage.

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: An optical signal sending apparatus includes an optical modulator, a differential driver, and a phase modulator. The optical modulator includes an optical input end, a first modulation region, a connection region, a second modulation region, and an optical output end. The first modulation region includes a first modulation arm and a second modulation arm. The second modulation region includes a third modulation arm and a fourth modulation arm. Each modulation arm includes an optical waveguide and electrodes on two sides of the optical waveguide. A differential drive signal is used to drive the two modulation regions, so that photoelectric signal modulation is implemented. The modulation arms are arranged in a stacked manner, so that a size of the optical modulator can be greatly reduced, thereby facilitating miniaturization.
