英文摘要 | PURPOSE:To obtain a semiconductor laser which can effectively enclose a current in an active layer, generate a laser oscillation with a less current and efficiently convert the current into a light by disposing the inner end of a third region which forms a current narrowing layer under an active region. CONSTITUTION:A first conductivity type first region 3, an active region 2 of a predetermined width for forming a junction with the region 2, a second conductivity type second region 1 for forming a junction with the region 2, a second conductivity type third region 4 in contact with the end of the region 2, and a fourth region 5 for forming a p-n junction with the region 4 are provided. A current narrowing layer is formed of the regions 3, 4, 5, and the inner end of the region 4 for forming the current narrowing layer is disposed under the region 2. For example, the region 3 is of a P-type InP clad layer, the region 2 is of an InGaAsP active layer 2, the region 1 is of an n-type InP clad layer, the region 4 is of an n-type InP current narrowing layer 4, and the region 5 is of a P-type InP current narrowing layer. |
