    • In the first method, an etching stop layer and a current blocking layer are grown on a semiconductor substrate by MOVPE. Next, the current blocking layer is etched on a region of the etching-stop layer corresponding to an active region, and the active region is formed in the etched portion by the selective growth using MOVPE. In the second method, a ridge is formed on a semiconductor substrate, and a doublehetero structure is grown on the ridge by MOVPE. On the active layer, a p-cladding layer is grown to be covered on the whole surface with (111) B plane entirely. The (111) B plane has the growth speed suppressing effect, so that no semiconductor layer is grown on the p-cladding layer, while a current blocking layer is grown on other regions.
    • 在第一种方法中,通过MOVPE在半导体衬底上生长蚀刻停止层和电流阻挡层。 接下来,在对应于有源区的蚀刻停止层的区域上蚀刻电流阻挡层,并且通过使用MOVPE的选择性增长在蚀刻部分中形成有源区。 在第二种方法中,在半导体衬底上形成脊,通过MOVPE在脊上生长双重结构。 在有源层上,生长p覆层以在整个表面上覆盖(111)B面。 (111)B面具有生长速度抑制效果,使得在p包覆层上不生长半导体层,而在其它区域上生长电流阻挡层。
