| 英文摘要 | The disclosed unipolar quantum cascade (QC) laser comprises a multiplicity of essentially identical active regions, with adjacent active regions separated by a superlattice carrier injection/relaxation region (11). A given active region (10) contains a single quantum well (13) with at least two electron states. Lasing is obtained without global intersubband population inversion. Instead, there is believed to exist local population inversion in a small region of k-space near k=0, corresponding to electron energies approximately within an optical phonon energy (∼35meV) from the bottom of the lower subband. A design feature that can be used to improve the thermal characteristics of substantially any QC laser is also disclosed. |
