Abstract: Embodiments of this application disclose an optoelectronic component and a fabrication method thereof. The optoelectronic component includes a capacitor, an inductor, a carrier component, and an optoelectronic element, where the capacitor, the inductor, and the optoelectronic element are all disposed on the carrier component. The inductor and the capacitor are configured to form a resonant circuit, where a resonance frequency of the resonant circuit is correlated with a signal output frequency of the optoelectronic element. A first electrode of the optoelectronic element is connected to a first electrode of the carrier component through the inductor, and a second electrode of the optoelectronic element is connected to a second electrode of the carrier component. A first electrode of the capacitor is connected to the first electrode of the carrier component, and a second electrode of the capacitor is connected to the second electrode of the carrier component.
