    Abstract: The present disclosure provides an optoelectronic component for a LiDAR system including a photonic integrated circuit. The photonic integrated circuit further includes a microresonator which is configured as an external resonator for an optical gain medium and to provide a frequency-modulated optical transmission field. A waveguide is optically coupled to an output side of the microresonator. A coherent in-line balanced detector comprises an electrical output, as well as a first optical connection side which is coupled to the waveguide to receive the transmission field, and a second optical connection side which is configured to receive a frequency-modulated optical reflection field. The coherent in-line balanced detector is further configured to superimpose the transmission field and the reflection field and to provide an electronic combination signal at the electrical output.

    Abstract: An optoelectronic component for a LiDAR module includes a carrier, a laser light source, and a detector element. The laser light source is designed for the generation of coherent electromagnetic radiation of a wavelength L1. The detector element is designed for coherent detection of incoming electromagnetic radiation of the wavelength L1 depending on a local oscillator signal. The laser light source and the detector element are arranged opposite one another on different sides of the carrier such that, during operation, electromagnetic radiation generated from the laser light source is coupled into the detector element via a first main surface through the carrier as the local oscillator signal and is coupled out via a second main surface.
