Abstract
PURPOSE: To extend the life time of laser function by protecting unnecessary current flow into junction part with setting the semiconductor laser device and first lock-in layer as n or p-type and the active layer and second layer as the opposite P or N- type.
CONSTITUTION: The first lock-in layer 2, the active layer 3 of In1-XGaXASYP1-Y (but, 0.05≤X≤0.47 and 0.1≤Y≤1) and the second lock-in layer 4 of InP are formed orderly on the InP base with liquid phase epitaxial growing method, and further, the electrodes 5 and 6 are formed on the opposite side to the lock-in layer 2 of base 1 and the opposite side to the active layer 3 of lock-in layer 4. To the case of the base 1 and the lock-in layer 2 being N or P-type, the active layer 3 and the lock-in layer 4 are set to the opposite p or n-type. With this method of stopping unnecessary current flow into the junction part 7, the life time of laser function is able to extend.
