  • Abstract
    Buried heterostructure quantum cascade lasers emitting at 5.64 μm are presented. Continuous-wave (CW) operation has been achieved at -30°C for junction down mounted devices with both facets coated. A 750 μm-long laser exhibited 3 mW of CW power with a threshold current density of 5.4 kA/cm2.
