Patent

CA 2437433

The invention concerns an optoelectronic device comprising first means (12, 13) defining a first thick resonant cavity (11) having a multiple transmission resonant modes, second means (18, 19, 37) defining a second thin resonant cavity (17) having one transmission resonant mode, means (38, 39) for optically coupling the first and second means, and electrostatic means designed to apply to the second means (18, 19, 37) an electric voltage selected to vary the thickness of the second cavity (17) and the spectral position of its resonant mode, such that it coincides with one of the resonant modes of the first cavity (11).

Un dispositif optoélectronique comprend des premiers moyens (12, 13) définissant une première cavité résonante épaisse (11) présentant une multiplicité de modes résonants de transmission, des seconds moyens (18, 19, 37) définissant une seconde cavité résonante mince (17) présentant un mode résonant de transmission, des moyens (38, 39) de couplage optique des premiers et seconds moyens, et des moyens électrostatiques agencés pour appliquer aux seconds moyens (18, 19, 37) une tension électrique choisie pour faire varier l'épaisseur de la seconde cavité (17) et la position spectrale de son mode résonant, de sorte qu'il coïncide avec l'un des modes résonants de la première cavité (11).
