| Outline of Final Research Achievements |
Interband mid-infrared lasers based on PbTe and PbS quantum wells and far-infrared quantum cascade lasers in the 25-50μm region were studied. Heteroepitaxial growth of PbTe and PbS based films and quantum wells on Si substrate with high thermal conductivity was successfully performed, and room-temperature pulsed laser operation was obtained in SrS/PbS quntum-well system. In quantum cascade lasers, stable growth of low carrier concentration quantum well is necessary, and we proposed EuTe/PbSnTe:In quantum well system in which In impurity level can keep the low carrier concentration.
