Abstract
A tuning arrangement for a vertical-cavity surface-emitting laser (VCSEL) may include a delta sigma modulator and a current source. The delta sigma modulator may be configured to generate a bitstream comprising bit signals, and the current source may be configured to provide a current to the VCSEL in a switchable manner depending on a control signal. The bitstream is generated based on a target state signal and the control signal corresponds to or is derived from the bit signals of the bitstream.
