| 英文摘要 | PURPOSE:To establish easily an angle (thetart. angle) spreading in the vertical direction of a laser beam so that its spread of the angle is superior in controllability and reproducibility by making the sum of thicknesses of clad layers which are provided on both sides of the first active layer smaller than that of the clad layers which are provided on both sides of the second active layer. CONSTITUTION:A p-type Ga0.86Al0.15As active layer 5c having a uniform thickness, a thick n-type Ga0.25Al0.48As the second clad layer 6a, and a thin n-type Ga0.52Al0.52As the second clad layer 6b are provided. The sum of thicknesses of clad layers 6b and 4 that are provided on both sides of the first active layer 5c is allowed to become smaller than that of thicknesses of clad layers 6a and 4 that are provided on both sides of the second active layer 5c. This approach makes a plurality of lasers in an element hold each angle (thetart. angle) spreading in the vertical direction of each different laser beam. |
