摘要： A method for manufacturing a surface-emitting laser array device is disclosed. In order to control the polarization characteristics of the surface-emitting laser, the surface-emitting laser array device according to the present invention can be manufactured by alternately arranging the surface-emitting laser formed by inclining a cavity in the and direction in accordance with the row or the column direction of the surface-emitting laser, so that the polarization characteristics of the surface-emitting laser in two directions which are relatively perpendicular to each other may be obtained. According to the present invention, it has an advantageous effect that the interaction between the adjacent laser beams can be minimized with maintaining the symmetric feature of the lasing beam when manufacturing an integrated surface-emitting laser array device. Further, since the traveling direction of the lasing beam can be controlled depending upon the polarization characteristics, not only the optical interconnection or optical switching can easily be performed, but also the device can effectively be applied to the device, for example, the magneto-optic disk which is sensitive to the polarization characteristics.

摘要： Disclosed is an ultrafast optical switching device having two types of multiple quantum well structures to be connected with each other, the device comprising a semi-insulating substrate; and a first and a second multiple quantum well structure formed sequentially on the substrate and united with each other to produce a double-junction multiple quantum well structure. Each of the multiple quantum well structures has nonlinear optical effects and two life time constants present while switching off in the device. One of the life time constants corresponds to a short life time constant to be determined dependent on electrons in the double-junction multiple quantum well structure and the other of the life time constants corresponds to a long life time constant to be determined dependent on holes and lattices therein. The multiple quantum well structures are formed in such a manner that short life time constants thereof may be in-phase with each other and long life time constants thereof may be out-of-phase to each other. The multiple quantum well structures are formed differently from each other in composition.
