The dependence of waveguide design parameters on the performance of a GaAs=AlGaAs quantum cascade laser emitting at 77 m is theoretically evaluated. We propose a new waveguiding scheme for modal conÿnement at such long wavelengths. An artiÿcially tailored index layer and a plasmon enhanced layer act
