| 英文摘要 | The core of the disclosed novel quantum cascade (QC) laser comprises a multiplicity of nominally identical repeat units, with a given repeat unit comprising a superlattice active region and a carrier injector region. Associated with the superlattice active region is an upper and a lower energy miniband, with the lasing transition being the transition from the lower edge of the upper miniband to the upper edge of the lower miniband. The injector facilitates carrier transport from the lower miniband to the upper miniband of the adjacent downstream repeat unit. QC lasers according to this invention can be designed to emit in the infrared, e.g., in the wavelength region 3-15 mu m, and can have high power. |
