Abstract
The present invention relates to an optoelectronic chip for receiving a sample for optical examination, having a carrier layer, a thin-film lightguide having an active region, in which the sample interacts with a guided mode of the thin-film lightguide, wherein at least one scattering structure is arranged in the active region, which scatters a part of the light guided in the thin-film lightguide, whereby a reference light field is produced. The invention further relates to an optical system having such a chip. The system is used for the marker-free analysis of particles, particularly biomolecules in their natural environment.

An optoelectronic chip for receiving a sample for optical examination, having a carrier layer, a thin-film lightguide having an active region, in which the sample interacts with a guided mode of the thin-film lightguide, wherein at least one scattering structure is arranged in the active region, which scatters light guided in the thin-film lightguide, whereby a reference light field is produced, wherein the chip further comprises a periodic structure within the active region.
An optoelectronic chip for receiving a sample for optical examination, having a carrier layer, a thin-film lightguide having an active region, in which the sample interacts with a guided mode of the thin-film lightguide, wherein at least one scattering structure is arranged in the active region, which scatters light guided in the thin-film lightguide, whereby a reference light field is produced, further comprising at least two coupling regions;
- one for coupling in the mode guided in the thin-film lightguide and one for coupling out a part of the mode guided in the thin-film lightguide from the thin-film lightguide for monitoring intensity of the guided mode.
