Abstract: An optical module includes a body and at least one heat dissipation structure. The body has a first end face and a second end face. The first end face of the body has at least one of an optical interface or an electrical interface, and the second end face faces opposite to the first end face. The at least one heat dissipation structure is located on the second end face and/or a side face of the body and can dissipate heat on a surface of the body.

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.
