英文摘要 | Disclosed are a gain coupled distributed feedback type semiconductor laser device which has a high single-mode yield and a smaller variation in the oscillation threshold current and luminous efficiency, and a method of manufacturing the same. The semiconductor laser device has a gain or loss which periodically changes, and comprises a cavity; and a diffraction grating formed in the cavity in such a way that an absolute value of a gain coupling coefficient in a vicinity of at least one of facets of the cavity is smaller than an absolute value of a gain coupling coefficient in the other area. |
