Title:
OPTOELECTRONIC SEMICONDUCTOR COMPONENT, OPTOELECTRONIC SEMICONDUCTOR DEVICE AND LIDAR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/053349
Kind Code:
A3
Abstract:
An optoelectronic semiconductor component (10) comprises a semiconductor layer stack (109), in which a surface-emitting laser diode (103) is arranged, and a modulating device (140) having a current source (149). The modulating device (140) is suitable for modifying a current strength injected into the surface-emitting laser diode (103), thereby making it possible to modify an emission wavelength.
