COMBINAISON GUIDE D'ONDES/DETECTEUR

摘要

A detector in which a wave guide 2 directs optical radiation onto a light-sensitive surface 4 of the detector is arranged parallel to the wave guide 2 in such a way that the evanescent or transient part of the radiation conducted in the wave guide 2 is coupled directly into the detector. Preferably the detector includes a transparent electrode 3 which is dimensioned such as to protrude laterally beyond the detector film 4. A first metal contact 5 may be applied directly to the detector film 4 and a second metal contact 7 may be applied to the protruding region of the electrode 3.
