CA 2592983

The invention concerns a wavelength-tunable selective optoelectronic filter, comprising a resonant cavity arranged between two partial reflectors (10, 12) such as Bragg mirrors, the resonant cavity consisting of a disc (16) made of solid material with high refractive index which constitutes a waveguide between the two partial reflectors (10, 12). Said filter exhibits excellent selectivity.

Filtre optoélectronique sélectif et accordable en longueur d'onde, comprenant une cavité résonnante placée entre deux réflecteurs partiels (10, 12) tels que des miroirs de Bragg, la cavité résonnante étant formée d'un disque (16) de matériau solide à indice de réfraction élevé qui constitue un guide d'onde entre les deux réflecteurs partiels (10, 12). Ce filtre présente une excellente sélectivité.
