Linewidth enhancement factor of terahertz quantum cascade lasers
Richard P. Green, Ji-Hua Xu, Lukas Mahler, Alessandro Tredicucci, Fabio Beltram et al.
The linewidth enhancement factor (LEF) of terahertz quantum cascade lasers is measured using an optical feedback self-mixing technique. As expected, a much lower LEF is found than is common for interband lasers, but instead of the predicted value of zero, the LEF depends on the laser conditions and ... [Appl. Phys.
