| abstract | (57) [Summary] [PROBLEMS] To realize a lower threshold value without lowering the luminous efficiency of a semiconductor laser and further improve the temperature characteristics. SOLUTION: Ga 0.5 In 0.5 P is formed at the center of an active layer 5. A multiple quantum well layer 52 in which quantum well layers and (Al 0.6 Ga 0.5 ) 0.5 In 0.5 P barrier layers are alternately stacked is arranged. On top of this multiple quantum well layer 52, a thickness of 30 nm The p-side light guide layer 53 is disposed. The p-side light guide layer 53 has a thickness d of a first light guide layer (intrinsic light guide layer) 53i to which an impurity is not intentionally added and a second light guide layer 53p to which a p-type impurity (Zn) is added. Light guide layer (p (Light guide layer) 53p. further, Below the multiple quantum well layer 52, a third light guide layer (n-side light guide layer) 51 having a thickness of 30 nm to which no impurity is intentionally added is disposed. The thickness d is selected to be 1 to 40 molecular layers. |
