英文摘要 | PURPOSE:To form a diffraction grating in an active layer and to obtain a longitudinal mode oscillation of a single wavelength by so growing an active layer as to further fill up a recess with a thin buffer layer on the surface of a semiconductor layer engraved with an uneven part. CONSTITUTION:A special semiconductor layer 4 is provided on a clad layer 3, and an uneven part corresponding to a diffraction grating is engraved thereon. A buffer layer 6 is grown by an organic metal vapor growing method on the uneven part while conserving the shape of the grating. Further, an active layer 7 is so grown as to bury the recess of the uneven part. Thus, the grating can be formed on the lower surface of the layer 7. Even if the grating is formed on the active layer by the above method, no defect occurs in a semiconductor crystal structure, an oscillation mode is stable without 2-mode oscillation, and its structure and manufacturing steps are simple. |
