Abstract

We report our recent experimental results on mid-infrared InAs-based quantum cascade lasers grown on n-InAs(100) substrates by molecular beam epitaxy. An InAs double plasmon waveguide is used for the optical confinement. The completed QCLs operate at 8-14 m wavelength range. Observed minimum threshold current density at 80 K by using InAs/AlGaSb superlattice active layers is 0.42kA/cm2, which is the lowest threshold current density in the mid-infrared region. The observed maximum operation temperature is 270K.
