Gain-shaped terahertz quantum cascade laser frequency combs
We demonstrate that adding carefully engineered resonant loss to a quantum cascade laser cavity can counteract the diffusive effect of the gain medium, allowing broader bandwidth combs to form. An improvement of 30\% in comb bandwidth is reported.
