Title: Strained quantum well semiconductor laser and its manufacture
Inventor: OTSUKA NOBUYUKI
IPC: H01S5/00
Filed: 1991-06-24
Abstract: PURPOSE:To improve the laser characteristic of a strained quantum well semiconductor laser by introducing a compressive strain to a well layer as an reaction to a tensile strain produced in a barrier layer having a lattice constant smaller than those of a substrate and the well layer by using the barrier layer. CONSTITUTION:An InP substrate 1 and well layer 4 have the same lattice constant and the lattice constant of a barrier layer 3 is smaller than that of the substrate 1 and layer 4. However, the lattice constants practically become the same in the planar direction, since the crystal lattices of the substrate 1 and layers 3 and 4 must be continuously coupled, and a tensile stress is produced in the barrier layer 3 by the expanded amount of the layer 3. As a result, the barrier layer 3 tends to contract to its original size and the well layer 4 contracts so that the layer can be balanced with the layer 3 in stress while the layer 4 is drawn by the layer 3. Consequently, the tensile strain in the layer 3 is relieved and a compressive strain is generated in the layer 4 by the contracted amount. Therefore, the film thickness condition of the well layer 4 can be relieved and the laser characteristic of this strained quantum well semiconductor laser can be improved.

Title: Amorphous magnetic multilayer thin-film
Inventor: KOBAYASHI KIKUO
IPC: H01F41/18
Filed: 1982-09-02
Abstract: PURPOSE:To improve uniformity extending over a large area, and to write a small bit stably by forming at least two layers consisting of a film attached through a bias sputtering method and a film attached through a zero-bias sputtering method on a substrate. CONSTITUTION:A first layer film 2 is formed on a substate 1 through a bias sputtering method, and a layer 2 is recorded. A second layer 3 is a film prepared on the layer 2 through the zero-bias sputtering method, and works to the first layer 2 and functions as the increase of the coercive force of the layer 2. The film 2 is excellent in uniformity extending over a large area, and has property in which the small bit of an approximately 1mum diameter can be written stably because it is made of two layer films. The magnetic thin-film having coercive force optimum as a photomagnetic recording medium can be obtained by changing the thickness of the two layer films-that is, by properly altering sputtering time.
