Abstract
(EN)
Provided is a light-emitting element having: a first active layer that emits light having a first wavelength by injecting a current; a second active layer that emits light having a second wavelength different from the first wavelength by absorbing the light having the first wavelength; and a first reflective mirror at which the reflectance of the light having the first wavelength is greater than the reflectance of the light having the second wavelength, wherein the first reflective mirror is disposed at a position closer to an emission end, from which the light emitted by the first active layer or the second active layer is projected outside, than to the first active layer and the second active layer.
(FR)
L'invention concerne un élément électroluminescent comprenant : une première couche active qui émet de la lumière ayant une première longueur d'onde par injection d'un courant ; une seconde couche active qui émet de la lumière ayant une seconde longueur d'onde différente de la première longueur d'onde par absorption de la lumière ayant la première longueur d'onde ; et un premier miroir réfléchissant au niveau duquel la réflectance de la lumière ayant la première longueur d'onde est supérieure à la réflectance de la lumière ayant la seconde longueur d'onde, le premier miroir réfléchissant étant disposé à une position plus proche d'une extrémité d'émission, à partir de laquelle la lumière émise par la première couche active ou la seconde couche active est projetée à l'extérieur, par rapport à la première couche active et à la seconde couche active.
(JA)
電流が注入されることにより、第1の波長の光を発する第1の活性層と、前記第1の波長の光を吸収することにより、前記第1の波長とは異なる第2の波長の光を発する第2の活性層と、前記第1の波長の光の反射率が前記第2の波長の光の反射率よりも高い第1の反射鏡と、を有し、前記第1の反射鏡は、前記第1の活性層及び前記第2の活性層よりも、前記第1の活性層又は前記第2の活性層で発せられた光を外部に射出する射出端に近い位置に配されている、発光素子が提供される。
