| 英文摘要 | A semiconductor optical element has a semiconductor substrate, a diffraction grating, a diffraction grating embedding layer, an active layer and a cladding layer. The diffraction grating includes a plurality of grating elements arranged on the semiconductor substrate along a direction (Z direction) in which laser light is emitted. Each grating element has a lower portion and an upper portion provided on the lower portion. The lower portions of the grating elements are connected to each other to form one layer in a lower section of the diffraction grating. The upper portion has a first refractive index and the lower portion has a second refractive index. A refractive index of the diffraction grating embedding layer is an intermediate value between the first and the second refractive index. |
