We demonstrate that an application of a III-V-on-silicon hybrid concept to terahertz (THz) Cherenkov difference frequency generation (DFG) quantum cascade laser (QCL) sources (THz DFG-QCLs) can dramatically improve THz output power and mid-infrared-t

We demonstrate that a heterogeneous integration of Cherenkov terahertz quantum cascade laser sources on a high-resistive silicon substrate enables 5 times improvement in terahertz power compared to that of devices on a native InP substrate.

We discuss novel approaches to improve the tuning bandwidth and power output of terahertz (THz) sources based on difference-frequency generation (DFG) in mid-infrared quantum cascade lasers (QCLs). Using a double Littrow external-cavity system, we ex

We report more than an order of magnitude improvement in the mid-IR-to-THz conversion efficiency in 1–3 THz sources based on intra-cavity difference-frequency generation in quantum cascade lasers designed to provide mid-infrared gain in 14∼15μm
