| 英文摘要 | A quantum cascade laser includes a semiconductor substrate including a principal surface; a mesa waveguide disposed on the principal surface of the semiconductor substrate, the mesa waveguide including a light emitting region and an upper cladding layer disposed on the light emitting region, the mesa waveguide extending in a direction orthogonal to a reference direction; and a current blocking layer formed on a side surface of the mesa waveguide. The light emitting region includes a plurality of core regions and a plurality of buried regions. The core regions and the buried regions are alternately arranged in the reference direction. The core region at a central portion of the mesa waveguide has a width larger than a width of the core region at a peripheral portion of the mesa waveguide in the reference direction. |
