Abstract
A quantum well optical device including a layer of semiconducting material of large forbidden band width and, situated in this layer, at least one quantum well, such as a quantum line or quantum hole, of a material having a narrower forbidden band than that of the layer. This quantum well has two permitted electron levels. Means exist of assuring the electron population of the first permitted energy level.
