Patent

CA 2444338

The invention concerns an electroluminescent device (1) comprising first (14) and second (5) substantially parallel mirrors (7) for converting electron-hole pairs into photons, and means for generating electrons and holes (6, 8). The converting means (7) and the first (14) and second mirrors (5) are designed to ensure the confinement between the first and second mirrors of photons having at least a selected wavelength, associated with a guided propagation mode. Additionally, the device comprises light extracting means (13) which communicate with part at least of the converting means and the generating means, comprised between the first and second mirrors, and are designed to extract therefrom part at least of the photons in guided mode, so that they reach outside.

Un dispositif électroluminescent (1) comprend des premier (14) et second (5) miroirs sensiblement parallèles et encadrant des moyens (7) de conversion de paires électron-trou en photons, et des moyens de génération d'électrons et de trous (6, 8). Les moyens de conversion (7) et les premier (14) et second (5) miroirs sont agencés de manière à assurer le confinement entre les premier et second miroirs des photons qui présentent au moins une longueur d'ondes choisie, associée à un mode de propagation guidé. Par ailleurs, le dispositif comprend des moyens d'extraction de lumière (13) qui communiquent avec une partie au moins des moyens de conversion et des moyens de génération, compris entre les premier et second miroirs, et sont agencés pour extraire de ceux-ci une partie au moins des photons dans le mode guidé, de sorte qu'ils parviennent à l'extérieur.
