    • An unipolar organic injection laser in which electrically-stimulated intraband transitions result in lasing. An active region (140) includes at least one organic injector layer (144) and at least one organic emitter layer (142). Each organic emitter layer has a first energy level and a second energy level on a same side of an energy gap defined by a conduction band and a valance band. Charge carriers are injected through the organic injector layer into the first energy level of the organic emitter layer when a voltage is applied across active region. The difference in energy between the first and second energy levels produces radiative emissions when charge carriers transition from the first energy level to the second energy level. Population inversion is maintained between the first and second energy levels, producing stimulated emission and lasing.
    • 单极有机注入激光器,其中电刺激的内部转换导致激光。 有源区(140)包括至少一个有机注入层(144)和至少一个有机发射极层(142)。 每个有机发射极层在由导带和价带限定的能隙的同一侧上具有第一能级和第二能级。 当在有源区域上施加电压时,电荷载体通过有机注入器层注入到有机发射极层的第一能级中。 当电荷载体从第一能级跃迁到第二能量级时,第一和第二能级之间的能量差异产生辐射发射。 在第一和第二能级之间维持人口倒数,产生受激发射和激光。
