Self-mixing interferometry and near-field nanoscopy in quantum cascade random lasers at terahertz frequencies
We demonstrate that electrically pumped random laser resonators, operating at terahertz (THz) frequencies, and comprising a quantum cascade laser heterostructure, can operate as sensitive photodetectors through the self-mixing effect. We devise two-dimensional cavities exploiting a disordered arrang...
