    Quantum cascade laser (QCL) optical frequency combs [1] , [2] are emerging as promising sources in mid-infrared spectroscopy due to their ability to act as coherent broadband sources at room temperature with equidistant phase-locked modes. Their short sub-picosecond upper-state lifetime enables high modulation speeds of the device in the order of tens of gigahertz [3] . Since the devices are electrically driven, the intermode beating, which is in the RF-domain, can be read out electronically as current-modulations. Through external RF-modulation of the driving current, the comb-modes can be injection-locked for stabilization as well as enhancement of the four-wave-mixing process which is one of the main driving mechanisms of comb formation in QCLs [5] .

    A terahertz quantum cascade laser design that combines a wide gain bandwidth, large photon-driven transport and good high-temperature characteristics is presented. It relies on a diagonal transition between a bound state and doublet of states tunnel coupled to the upper state of a phonon extraction stage. The high optical efficiency of this design enables the observation of photon-driven transport over a wide current density range. The relative tolerance of the design to small variations in the barrier thicknesses made it suitable for testing different growth techniques and materials. In particular, we compared the performances of devices grown using molecular-beam epitaxy with those achieved using organometallic chemical vapor deposition. The low-threshold current density and the high slope efficiency makes this device an attractive active region for the development of single-mode quantum cascade lasers based on third-order-distributed feedback structures. Single-mode, high power was achieved with good continuous and pulsed wave operation.
