Abstract

L'invention concerne un dispositif optoélectronique (30) comprenant une zone active (18) adaptée à fournir un rayonnement électromagnétique et prise en sandwich entre des première et deuxième couches semiconductrices (14, 32), la première couche semiconductrice délimitant une face (38) et comprenant une première portion (34) au contact de zone active et délimitant une première partie (40) de la face et se prolongeant par une deuxième portion (36) délimitant une deuxième partie (42) de la face, la deuxième portion formant un guide d'onde monomode, le dispositif optoélectronique comprenant une portion (44) opaque et réfléchissante au rayonnement électromagnétique recouvrant la première partie et comprenant un réseau de diffraction (46) sur la deuxième partie adapté à extraire le rayonnement électromagnétique de la deuxième portion selon une direction sensiblement perpendiculaire à la première partie à 10° près.
