We present the design and optimization of a deep-well GaAs-based quantum cascade laser (QCL) emitting at 6.7 μm, the shortest wavelength in GaAs-based QCLs, using a multivalley Monte Carlo simulation. The simulation is performed self-consistently with the design process. The optimized structure exhibits sufficient gain to achieve lasing at both 77 K and 300 K. The calculated threshold currents are 5 kA/cm2 at 77 K and 14 kA/cm2 at 300 K.
