    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.
