Title (EN) RESONANT MICROCAVITIES
(FR) MICROCAVITES RESONANTES
Abstract:
(EN) A condensed matter structure (10) includes a substrate (12) having a resonant microcavity (11) formed by reflectors (14, 15), having a reflectivity R, arranged relative to an optically-active material (16) to form a cavity. The optically-active material (16) has a thickness L, an optical emission line centered at a wavelength $g(l)c, and an optical absorption coefficient $g(a)0 at $g(l)c. The magnitude of the absorption ($g(a)0L) at $g(l)c by the optically-active material (16) is greater than the probability (1-R) that an electromagnetic field having an energy of $g(l)c exits microcavity (11) and thereby results in a strong light-matter interaction between the optically-active material (16) and the electromagnetic field confined in the microcavity (11).
(FR) L'invention porte sur une structure (10) de matière condensée comprenant un substrat (12) pourvu d'une microcavité (11) résonante formée par des réflecteurs (14, 15) ayant une réflectivité R, et agencés par rapport à un matériau (16) optiquement actif de façon à former une cavité. Le matériau (16) optiquement actif a une épaisseur L, une ligne d'émission optique centrée à une longueur d'onde $g(l)c, et un coefficient d'absorption optique $g(a)0 à $g(l)c. L'amplitude d'absorption ($g(a)0L) à $g(l)c par le matériau optiquement actif (16) est supérieure à la probabilité (1-R) qu'un champ électromagnétique ayant une énergie de $g(l)c sorte de la microcavité (11) et entraîne donc une forte interaction lumière-matière entre le matériau (16) optiquement actif et le champ électromagnétique confiné dans la microcavité (11).
