摘要:
A semiconductor optical apparatus of the invention has a quantum well super-lattice structure consisting of only a direct transition semiconductor or both of a direct transition semiconductor and an indirect transition semiconductor. In the semicondcutor optical apparatus of the invention, by using an absorption saturation phenomenon of excitons in the direct transition semiconductor constructing the quantum well super-lattice structure, a non-volatile information recording apparatus which can record, reproduce, and erase informatin at a high speed even at the room temperature or even by irradiating a light of a low intensity is realized.
摘要:
In a buried type semiconductor laser device composed of a II-VI compound semiconductor, a buried layer 9 - 11 is made of a II-VI compound semiconductor having a refraction factor lower than that of an active layer of the laser device. The buried layer has a forbidden band width larger than that of an active layer of the laser device. The buried layer has such a composition that the lattice constant thereof is substantially matched to that of a substrate on which the laser device is grown. The buried layer has an electric resistance high enough not to exert an effect on the operation of the laser composed of an n-type clad-active layer-a p-type clad.
