Abstract: An optical sensor arrangement, for example for a LiDAR system, includes an emitter unit and a receiver unit. The emitter unit includes a semiconductor laser configured to emit coherent electromagnetic radiation having at least two wavelengths. Furthermore, the emitter unit is configured to direct the emitted electromagnetic radiation at a remote target, the receiver unit including at least one optical sensor configured to selectively detect electromagnetic radiation depending on the at least two wavelengths. The receiver unit is arranged relative to the emitter unit and configured such that electromagnetic radiation scattered or reflected by the remote target is detectable on the optical sensor.

Abstract: A radiation emitting device for emitting light may include a laser light source configured to emit light along an emitting direction, and a non-imaging optical system arranged downstream of the laser light source in the emitting direction. The optical system may include a plurality of optical elements arranged along the emitting direction for shaping a radiation characteristic of the radiation emitting device in a horizontal direction and a vertical direction perpendicular to the horizontal direction, such that the radiation characteristic is asymmetrical along the vertical direction. A first optical element of the optical system may be configured to cause spreading of the light along the horizontal direction; a second optical element of the optical system may be configured to cause collimation of the light along the vertical direction, and a third optical element of the optical system may be configured to cause radiation asymmetry along the vertical direction.

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: A Lidar system may include a first laser, a second laser, and a detection unit for detecting laser radiation of the first and second lasers. The first laser in a first wavelength range and the second laser in a second wavelength range may be configured for periodically tuning a respective emission wavelength. A first tuning time T1 of the first laser may differ from a second tuning time T2 of the second laser.

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.

Abstract: An optical measuring device, in particular for a motor vehicle, includes a laser device designed to generate a single-mode laser beam whose frequency can be modulated and a controllable optical modulator designed for adjustable amplitude modulation of the frequency-modulated single-mode laser beam generated by the laser device. The measuring device also contains a detector device designed to receive part of the frequency-modulated single-mode laser beam generated by the laser device for superimposition with an amplitude- and frequency-modulated single-mode laser beam reflected by an object. An evaluation circuit is designed to transmit the signal superimposed by the detector device into the frequency domain and to determine the distance and speed of an object reflecting the single-mode laser beam.
