英文摘要 | PURPOSE:To maintain a single-humped beam up to a high output and to obtain high reliability by providing no active stripe region due to Zn diffusion, etc., near a reflecting surface, and increasing the inhibited band width of a non- diffused region near the reflecting surface larger than a diffused region. CONSTITUTION:A light is guided via a waveguide formed of a refractive index difference in the lateral direction due to Zn diffusion and a refractive index difference between upper, lower clad layers 4, 2 and an active layer 3 in a resonator to form an array laser. On the other hand, the light is guided verti cally by a refractive index difference between the layers 4, 2 and the layer 3 in the vicinity of an edge in which no Zn is diffused, i.e., a non-diffused n-type window region 9, a guiding mechanism is not provided horizontally, and a diffraction coupling is formed. Further, the inhibited band width of the region 9 is increased larger than a p-type stripe region 8 in which Zn is diffused due to an acceptor order caused by Zn diffusion so that a laser light is not absorbed by the region 9. |
