| 英文摘要 | PCT No. PCT/JP91/01418 Sec. 371 Date Jun. 17, 1992 Sec. 102(e) Date Jun. 17, 1992 PCT Filed Oct. 17, 1991 PCT Pub. No. WO92/07401 PCT Pub. Date Apr. 30, 1992.This invention relates to a distributed feedback semiconductor laser which achieves distributed feedback by gain coupling by providing periodical changes in the thickness of the active layer (5) or the absorptive layer, and aims to achieve light distributed feedback mainly of periodical perturbation of the gain factor by diminishing the periodical perturbation of refractive index caused by the changes in the thickness of the active layer (5) or the absorptive layer. This invention is characterized by a refractive index canceling structure comprising a combination of layers (6) and (7) of different refractive indices to cancel periodical changes in refractive index caused by the periodical structure of the active layer (5) or the absorptive layer. |
