Abstract

An optoelectronic module comprising at least one semiconductor laser and a photonic chip is described herein. The semiconductor laser emits a primary electromagnetic radiation which is coupled into the photonic chip. The photonic chip comprises at least one first waveguide and at least one optical Bragg reflector having a reflectivity which is modulated by an electrical modulation signal. A secondary electromagnetic radiation is coupled out of the photonic chip by means of at least one second waveguide, wherein the secondary electromagnetic radiation has a dominant wavelength which is modulated in dependence of the electrical modulation signal. Further, a method for operating an optoelectronic module and a Head-Mounted Display comprising an optoelectronic module are provided.
