英文摘要 | PURPOSE:To enable a face light emitting semiconductor laser to surely execute a basic mode oscillation and to be integrated high in density by a method wherein active regions making gains and regions making no gain are alternately disposed in periodic arrangement to constitute a horizontal active waveguide, and a total reflection end face inclined at an angle of 45 deg. is provided to the end of a laser oscillation main body. CONSTITUTION:Active regions 30 where gain is made and regions 36a where no gain is made are periodically arranged to form a horizontal active waveguide 54 in parallel with the upside of a substrate in a laser oscillation main body 56, total reflection end faces 50 and 52 inclined at an angle of 45 deg. are provided to the end of the laser oscillation main body 56, a multilayered reflective film 14 of high reflectivity is provided under a lower clad layer 16, and a resonator is constituted between the lower reflective film 14 and an emission window 62. Viewing a resonator from a plane parallel with the upside of the substrate 10, a distance between reflective planes which form the resonator is short, s that a semiconductor laser can be highly integrated. Furthermore, a current can be injected into active layer regions from the upper electrode 46 to start laser oscillation, and as a region 36a is provided, a semiconductor laser of this design can be restrained from increasing in threshold current even if a resonator is formed short in length. |
