光器件包括三个耦合的量子阱结构

Optical device including three coupled quantum well structure
Abstract:
Provided is an optical device which includes an active layer which includes at least two outer barriers and at least one coupled quantum well, each of the at least one coupled quantum well is sandwiched between the at least two outer barriers. Each of the at least one coupled quantum well includes at least three quantum well layers and at least two coupling barriers interposed between the at least three quantum layers. The at least two coupling barriers have a potential energy which is higher than a ground level and is lower than energy levels of the at least two outer barriers.
Abstract(Chinese):

提供了一种光学器件，其包括有源层，该有源层包括至少两个外部屏障和至少一个耦合量子阱，所述至少一个耦合量子阱中的每一个被夹在所述至少两个外部屏障之间。 所述至少一个耦合量子阱中的每一个包括至少三个量子阱层和插入在所述至少三个量子层之间的至少两个耦合屏障。 所述至少两个耦合屏障具有高于地平面并且低于所述至少两个外部屏障的能量水平的势能。
