Abstract
The invention concerns a semiconductor opto-electronic component comprising at least two optically active structures (20, 30), at least one of which consists of a detector (30), characterized in that the detector or detectors (30) comprise a first active portion (33) able to detect a signal at a given wavelength and a second inactive portion (34) only slightly sensitive to the signal to be detected and exposed to the non-guided stray light conveyed in the component.
