| 英文摘要 | The invention is a semiconductor laser, laser module, and method of manufacture. The laser includes an active region having a first refractive index, and at least one confinement layer with a second refractive index, which is lower than the first refractive index. An anti-guiding layer having a third refractive index which is lower than the second refractive index is positioned so that the confinement layer is between the active region and the anti-guiding layer. A cladding layer having a fourth refractive index which is greater than the third refractive index is positioned so that the anti-guiding layer is between the cladding layer and the confinement layer. |
