• A 540-640-GHz high-efficiency four-anode frequency tripler (2005, background): “cascade laser (QCL) technology [5] reaches maturity, QCLs could be used to create low-power all-solid-state terahertz”
• Recent Progress in Terahertz Quantum Cascade Lasers (2011, positive): “Whereas the initial demonstration of terahertz QCLs was done with the aid of a single-plasmon waveguiding scheme [5], the subsequent development of double-plasmon metal–metal waveguides [21] has led to higher operating temperatures in both pulsed (186 K) [22] and CW (117 K) [23], [24] operation.”
• Terahertz imaging using quantum cascade lasers—a review of systems and applications (2014, positive): “and low threshold current densities [51].”
