Abstract

Various embodiments may relate to an optoelectronic component, including an optoelectronic structure formed for providing an electromagnetic radiation, a measuring structure formed for measuring the electromagnetic radiation, and a waveguide formed for guiding the electromagnetic radiation. The optoelectronic structure and the measuring structure are optically coupled to the waveguide. The waveguide includes scattering centers distributed in a matrix, wherein the scattering centers are distributed in the matrix in such a way that part of the electromagnetic radiation is guided from the optoelectronic structure to the measuring structure.
