Homogeneous quantum cascade lasers operating as terahertz frequency combs over their entire operational regime

Homogeneous quantum cascade lasers operating as terahertz frequency combs over their entire operational regime

We report a homogeneous quantum cascade laser (QCL) emitting at terahertz (THz) frequencies, with a total spectral emission of about 0.6 THz, centered around 3.3 THz, a current density dynamic range Jdr = 1.53, and a continuous wave output power of 7 mW. The analysis of the intermode beatnote unveil...
