Abstract

The recent extension of quantum cascade lasers (QCLs) from the mid-infrared to the terahertz frequency range (1-10 THz) promises to help address the relative lack of compact, coherent radiation sources in this spectral regime. We report our recent development of terahertz QCLs based on a resonant phonon depopulation scheme coupled with high-confinement, low-loss, metal-metal waveguides for mode confinement. A 3.2 THz laser (λ≈ 93.4 μm) is presented that operates in continuous wave mode up to a temperature of 93 K and up to 133 K in pulsed mode. Also presented is a 2.1 THz laser (λ ≈ 141 μm) that lases up to 40 K in continuous wave mode and 72 K in pulsed mode.
