Abstract: An optoelectronic semiconductor chip having a semiconductor body (1) that is suitable for emitting electromagnetic radiation in a first wavelength range from a radiation exit face (3) is specified. Furthermore, the semiconductor chip comprises a ceramic or monocrystalline conversion platelet (6) that is suitable for converting electromagnetic radiation in the first wavelength range into electromagnetic radiation in a second wavelength range, which is different from the first wavelength range, and a wavelength-converting joining layer (7) that connects the conversion platelet (6) to the radiation exit face (3), wherein the wavelength-converting joining layer (7) has luminescent material particles (4) that are suitable for converting radiation in the first wavelength range into radiation in a third wavelength range, which is different from the first wavelength range and the second wavelength range. The wavelength-converting joining layer (7) furthermore has a thickness of no more than 30 micrometres. A method for fabricating an optoelectronic semiconductor chip, a further semiconductor chip, conversion element and luminescent material are specified.

Abstract: An optoelectronic device, in particular for the detection of obstacles and/or for distance measurement, may include a transmitting device for emitting laser beams. The transmitting device may include an array of pixels where each pixel of the pixel array comprises at least one laser, such as an optoelectronic laser, e.g. a VCSEL. The pixels of the pixel array may be divided into several sets of pixels, and the transmitting device may be configured to operate the sets of pixels in different, successive time intervals.
