Patent

CA 2475241

The invention relates to a class of photonic crystals that are similar to the known inverse opals while being characterized by so far not known band gaps or larger pseudo band gaps, especially between the 5th and 6th band and/or between the 8th and 9th band. The invention further relates to a method for producing said photonic crystals and to the use thereof as laser resonators, matrices for optical guides, opalescent pigments, beam splitters, spectral filters or as components of such devices.

L'invention concerne une classe de cristaux photoniques similaires aux opales inverses connues, mais présentant des largeurs de bande interdite ou de plus grandes largeurs de pseudobande interdite, inconnues jusqu'à présent, en particulier entre la 5ème et la 6ème bande et/ou entre la 8ème et la 9ème bande. L'invention concerne en outre un procédé d'obtention de cristaux photoniques et leur utilisation comme résonateurs laser, matrices pour guides d'ondes optiques, pigments opalescents, diviseurs de faisceau, filtres pour filtrage spectral, ou comme composants de tels dispositifs.
