Paper Abstract
Quantum cascade lasers (QCLs) are powerful testing grounds for the fundamental physical parameters determined by
their quantum nature. The associated wealth of unique physical properties makes the QCL a subject of extensive
research, especially across the far-infrared, where the electron-phonon relaxation dynamics, the gain mechanisms and
the related intrinsic QCL features need to be extensively investigated. Here, we report a complete overview of the
frequency-noise power spectral density of a THz QCL, giving an experimental and analytical evaluation of its intrinsic
linewidth and a full investigation of the physics beyond it, offering a new perspective of use of ultra-narrow THz QCL
sources as a metrological grade tool for a widespread range of photonic applications.
