Title: Semiconductor laser element
Inventor: TSUNEKANE MASAKI
IPC: H01S5/028
Filed: 1989-09-20
Abstract: PURPOSE:To obtain a semiconductor laser element which is high in yield and reliability, to restrain a surface level from being formed in an active layer at an end face as making the most of the feature of a laser structure, and to enable oscillation light not to be absorbed at the end face by a method wherein a semiconductor layer of high resistance whose forbidden band is larger than that of an active layer is provided to a cleavage plane vertical to a direction in which a resonator is provided. CONSTITUTION:A semiconductor layer 1 of high resistance whose forbidded band is larger than that of an active layer 5 is provided to a cleavage plane 2 vertical to a direction in which a resonator is provided. Therefore, the control of etching in depth and shape is not required, so that a semiconductor laser element becomes high in yield. Moreover, the cleavage plane 2 is free of contamination caused by an etching solution and flat of the order of an atomic layer, so that an interface between the active layer 5 and a semiconductor protective film is excellent in crystallinity and small in interface level and improved in reliability. The face of the semiconductor protective film is vertical to a direction in which an optical waveguide extends, so that the reduction of an optical coupling efficiency is small, and consequently the increase of a threshold current and the reduction of an emission efficiency can be minimized. By this setup, as the semiconductor protective film is of high resistance, the leakage current of a PN semiconductor layer through the intermediary of the film concerned hardly occurs, so that a semiconductor laser element of this design is prevented from deteriorating in characteristics and the absorption of oscillation light can be eliminated by using a semiconductor layer large in forbidden band.

IPC: B64G7/00
Filed: 1984-11-22
Abstract: PURPOSE:To obtain a test apparatus reduced in restriction in a gravity direction and added means effect, by hanging a cosmic structure by a long spring having a definite curvature. CONSTITUTION:One end of a long spring 1 having a definite curvature is fixed to a ceiling side support jig 2 and the other end thereof is fixed by wires 3. The wires 3 hangs up a structure 4 being an object to be tested in air. The support jig 2 consists of a fixed member 2a and a movable member 2b and the movable member 2b is displaced with respect to the fixed member 2a to regulate the length of each wire. Because the long spring 1 having the definite curvature receives almost constant tension regardless of a displacement amount, displacement is not restricted when a vibration test is performed. By this method, the same inherent vibration number and inherent mode as the vibration state in a cosmic space can be faithfully reproduced.
