英文摘要 | A semiconductor laser device of the double-hetero structure has a semiconductor substrate (4), a semiconductor active layer (1) and cladding layers (2,3) sandwiching the active layer (1). In order to achieve a laser which can operate at a short wavelength, e.g. about 0.6 µm, the substract (4) is GaAstP1-t (0.54 ≦ t ≦ 0) and the active layer (1) is GayIn1-yAsxP1-x (0.52 ≦ y ≦ 0 and 0 ≦ x ≦ 0). The first cladding layer (2) is GapAl1-pAsqP1-q (0 ≦ p ≦ 0.91 and 0.47 ≦ q ≦ 0) and the second cladding layer (3) is Gap,Al1-P,Asq,P1-q, (0 ≦ p' ≦ 0.91 and 0.47 ≦ q' ≦ 0). The two cladding layers (2,3) are of opposite conductivity type. The active layer (1) has an optical confinement region of refractivity higher than that of the cladding layers and a band gap narrower than that of the cladding layers. |
