A method and apparatus for enhanced optical emissions, the apparatus comprising a light source (12), a microcavity (14), and a medium comprising nanoparticles, located within or near the microcavity. The nanoparticles are either non-aggregated or are aggregated in the form of fractals. The nanoparticles and microcavity exhibit enhanced linear and non-linear optical parametric oscillation, light detection and ranging, increased sensitivity, high density optical data storage, and near-field optical spectroscopy.

La présente invention concerne un procédé et un appareil destinés à des émissions optiques améliorées, l'appareil comprenant une source de rayonnement lumineux, une microcavité, et un milieu contenant des nanoparticules, placé à l'intérieur ou au voisinage de la microcavité. Les nanoparticules ne sont pas agrégées ou sont agrégées sous la forme de fractales. Les nanoparticules et la microcavité manifestent une émission optique linéaire ou non linéaire améliorée. L'appareil à rayonnement lumineux peut être utilisé dans les domaines de la translation de longueur d'onde, de l'amplification, de l'oscillation de paramètre optique, de détection et de télémétrie à rayonnement lumineux, d'augmentation de sensibilité, de stockage optique haute densité, et de spectroscopie optique à champ proche.
