Title
(EN) LOW ONSET GAIN SATURATION OLED
(FR) OLED À SATURATION DE GAIN À FAIBLE APPARITION
Abstract
(EN)
Embodiments of this invention relate to and, more particularly, to solid state lighting, digital displays, conversion of electrical energy to light, low onset gain saturated stimulate emission, light production with high efficiency and high output per area, and light production while limiting material degradation, and may also be applied in optical or quantum information processing and networking. Embodiments of this invention comprise spectroscopic configurations having a radiative transition to a depopulated state and an optical configuration having sufficient Q such that the combination allows onset of gain saturation with a small excited state population or low current density, thus enabling production of light in a mode with near total output coupling, high efficiency, high output, low roll-off and attenuation of losses and degradation processes.

Des modes de réalisation de la présente invention concernent et, plus particulièrement, un éclairage à semi-conducteurs, des affichages numériques, une conversion d'énergie électrique en lumière, une émission de stimulation à saturation de gain à faible apparition, la production de lumière avec une efficacité élevée et un haut rendement par zone, et la production de lumière tout en limitant la dégradation de matériau, et peuvent également être appliqués au traitement et à la mise en réseau optique ou quantique d'informations. Les modes de réalisation de la présente invention comprennent des configurations spectroscopiques ayant une transition radiative vers un état dépeuplé et une configuration optique ayant un facteur de surtension Q suffisant de telle sorte que la combinaison permet l'apparition d'une saturation de gain avec une petite population d'état excité ou une faible densité de courant, ce qui permet la production de lumière dans un mode avec un couplage de sortie quasi total, une efficacité élevée, un haut rendement, un faible affaiblissement et une atténuation des pertes et des processus de dégradation.
