Title (EN) LED WITH CURENT CONFINEMENT STRUCTURE AND SURFACE ROUGHENING
(FR) DEL A STRUCTURE DE CONFINEMENT DE COURANT ET SURFACE RUGUEUSE
Abstract: front page image
(EN)An LED (10) having a p-type layer of material with an associated p-contact, an n-type layer of material with an associated n-contact and an active region (18) between the p-type layer and the n-type layer, includes a confinement structure (20) that is formed within one of the p-type layer of material and the n-type layer of material. The confinement structure (20) is generally aligned with the contact (22) on the top and primary emission surface of the LED (10) and substantially prevents the emission of light from the area of the active region (18) that is coincident with the area of the confinement structure and the top-surface contact (22). The LED (10) may include a roughened emitting side surface (25) to further enhance light extraction.
(FR)L'invention concerne une DEL (10) comprenant une couche de type p de matériau avec un contact p associé, une couche de type n de matériau avec un contact n associé et une région active (18) entre la couche de type p et la couche de type n, comprenant une structure de confinement (20) formée dans une des couches de type p et de type n de matériau. La structure de confinement (20) est, en général, alignée avec le contact (22) sur la surface d'émission supérieure et principale de la DEL (10) et empêche sensiblement d'émettre un rayonnement à partir de la zone de la région active (18) coïncidant avec la zone de la structure de confinement et le contact de la surface supérieure (22). La DEL (10) peut comprendre une surface latérale émettrice rugueuse (25), de manière à encore améliorer l'extraction lumineuse.
