摘要	A self-pulsation type semiconductor laser device includes a semiconductor substrate of a first conductive type and a multilayered structure including at least an active layer provided on the semiconductor substrate. The multilayered structure includes a first cladding layer of the first conductive type provided below the active layer, a second cladding layer of a second conductive type having a striped ridge portion provided above the active layer and a saturable absorbing film provided over the second cladding layer. The saturable absorbing film includes an accumulation region for accumulating photoexcited carriers. The accumulating region is provided apart from a surface of the second cladding layer.
其他摘要	一种自脉冲型半导体激光器件，包括第一导电类型的半导体衬底和至少包括设置在半导体衬底上的有源层的多层结构。该多层结构包括设置在有源层下方的第一导电类型的第一包层，第二导电类型的第二包层，其具有设置在有源层上方的条纹脊部分和设置在第二包层上的可饱和吸收膜。可饱和吸收膜包括用于累积光激发载流子的累积区域。累积区域与第二包层的表面分开设置。
