Abstract
PURPOSE: To enhance the laser characteristics, the yield and the reliability by providing the electrode and the active region near the groove part of the electrode forming crystal layer on the surface of the semiconductor laser crystal.
CONSTITUTION: Electrode forming crystal layers 14, 15, 16, 17 and 25 are provided on the surface of semiconductor laser crystal 13, along with groove part 26 formed by etching part of the electrode forming crystal layer. At the same time, electrodes 27 and 28 are formed near groove 26, and active regions 19 and 20 are provided under groove 26 respectively. Thus, the laser characteristics including the temperature property as well as the yild and the reliability can be enhanced.
