Summary
The terahertz (THz) frequency range in the electromagnetic spectrum lacks a compact semiconductor source of ultra-short pulses, suitable for applications including ultrafast spectroscopy, atmospheric science and stable THz frequency comb generation. Although the quantum cascade laser (QCL) is a promising compact semiconductor THz source, its success in creating ultra-short pulses is limited due to the inherent fast gain recovery time. There have been demonstrations of short pulse (>1 ps) generation from THz QCLs based on active modelocking, although the stability of the pulses is limited. Crucially, there has been no demonstration of passive modelocking of QCLs to date, which in principle can create pulses much shorter than 1 ps.
