CA 2324600

An integrated micro-optical system includes at least two wafers with at least two optical elements provided on respective surfaces of the at least two wafers. An active element having a characteristic which changes in response to an applied field may be integrated on a bottom surface of the wafers. The resulting optical system may present a high numerical aperture. Preferably, one of the optical elements is a refractive element formed in a material having a high index of refraction.

La présente invention concerne un système micro-optique intégré comprenant au moins deux plaquettes comportant chacune sur leur surface au moins deux élément optiques. On peut par ailleurs intégrer sur une surface inférieure des plaquettes un élément actif possédant une caractéristique qui se modifie en réaction à un champ appliqué. Le système optique ainsi obtenu peut présenter une grande ouverture numérique. De préférence, un des éléments optiques est un élément de réfraction fabriqué dans un matériau ayant un indice de réfraction élevé.
