| 英文摘要 | PURPOSE:To form a buried semiconductor laser element with multiaxis mode with a good reproducibility by a method wherein a width of a striped active layer which is buried are varied at each region. CONSTITUTION:A width of a striped active region 20 in a double heterojunction structure which is buried with a layer having a wide forbidden band width is arranged to be 2mum, and notches 21-24 with length of 3mum and depth of 0.5mum are provided to be distributed at random. Thereby while maintaining a substrate traverse mode, a semiconductor laser which oscillates stably in 3-5 axial modes can be obtained and it can be used in a multimode type optical fiber transmission system. |
