英文摘要 | PURPOSE:To decrease a leakage current and to enhance an optical output when an injection current is at a high level by a method wherein a double-hetero PN junction, a buried PN junction including an active layer, and a sudormorphic layer are provided. CONSTITUTION:A current is trapped in an active layer 3 through a diffusion potential difference between a double-hetero PN junction composed of the active layer 3 and clad layers 2 and 6 and a buried PN junction formed between a second semiconductor layer 6 and a fifth semiconductor layer 5. When a current injection is at a low level, the buried PN junction is not turned ON, so that no leakage current flows. When a current injection is enhanced in level, a voltage applied to the buried PN junction becomes high to enable a leakage current to start flowing. At this point, the pseudomorphic layer 4 functions as a barrier to prevent a leakage current from increasing. By this setup, a leakage current can be decreased and an optical output can be enhanced when a current injection is at a high level. |
