IPC: H01S5/00
Filed: 1996-02-13
Abstract: PURPOSE: To obtain the passivation method of a reflecting surface of semiconductor laser which is excellent in workability and mass-productivity, by forming a dielectric film from the side surfaces of a plurality of semiconductor layers containing an active layer laminated on a semiconductor substrate to the side surface of the semiconductor substrate, and forming a region in which the dielectric film is not formed, on the semiconductor substrate side surface. CONSTITUTION: On the surface of an N-type GaAs substrate 1, a belt type recessed trench is formed, on which an N-type GaAlAs clad layer 3, a GaAlAs active layer 4, a P-type GaAlAs clad layer 5 and an N-type GaAs cap layer 6 are formed. After that, a P side electrode 8 is formed. A photoresist film is used as a mask, and a resonator reflecting surface 11 is formed by a reactive ion beam etching method. The reflecting surface can be formed almost vertically. By using a sputter coating method, SiO2 10 is formed on the whole surface. In this case, SiO2 creeps over the resonator reflecting surface, and a passivation film is formed. A photoresist mask is formed, SiO2 on the P side electrode is eliminated, and an N side electrode is formed.

Abstract: PURPOSE:To conform the axis of the magnetic field and the beam axis easily and to improve the focusing of beams by adding two rotating mechanisms making the X-axis and the Y-axis as the axial centers, to the linear regulation mechanisms of X, Y, and Z axes. CONSTITUTION:The beam axis and the mechanical axis of an electromagnet 1 are conformed by sliding the electromagnet 1 longitudinally, laterally, and vertically by linear regulating mechanisms 2, 3, and 4 of the X, Y, and Z axes. Then by X and Y axes rotation driving devices 10 and 12, the magnet 1 is regulated at a desired angle at the point of the original point O, so as to conform the beam axis and the axis of the magnetic field of the magnet 1. In this case, a flux meter to detect only the diameter direction component of the magnetic field is inserted to the beam axis in order to conform the magnetic field of the magnet 1, and a rotary shaft 7 for X axis and a rotary shaft 6 for Y axis are rotated to make the diameter direction component zero. When the both axes are conformed while accelerating the beam, the magnet 1 is rotated to the shafts 7 and 6 so as to make the deflection of the beam zero by a remote control. Consequently, the axis of the magnetic field and the beam axis can be conformed easily, and a good beam focusing is realized.
