Title (EN) LIGHT-EMITTING DIODES (LEDS) WITH MONOLITHICALLY-INTEGRATED PHOTODETECTORS FOR IN SITU REAL-TIME INTENSITY MONITORING
(FR) DIODES ÉLECTROLUMINESCENTES (DEL) À PHOTODÉTECTEURS INTÉGRÉS MONOLITHIQUEMENT DESTINÉS À LA SURVEILLANCE D'INTENSITÉ EN TEMPS RÉEL IN SITU
Abstract:
(EN) Devices directed to light-emitting diode (LED) lighting applications and methods of fabricating the same are provided. A device can include an LED integrated with a photodetector on the same semiconductor platform, such that the photocurrent generated by the photodetector can be used to monitor the optical output of the LED, which is located adjacent to the photodetector. Compact, robust, and reliable photodetectors capable of monitoring LED emission via a low-cost approach are provided.
(FR) L'invention porte sur des dispositifs destinés à des applications d'éclairage par diodes électroluminescentes (DEL) et sur leurs procédés de fabrication. Un dispositif peut comprendre une DEL intégrée à un photodétecteur sur la même plate-forme de semi-conducteur, de manière que le courant photoélectrique généré par le photodétecteur puisse être utilisé pour surveiller la sortie optique de la DEL, qui est située adjacente au photodétecteur. Des photodétecteurs compacts, robustes et fiables aptes à surveiller l'émission de DEL sont obtenus par le biais d'une approche à bas coût.
