Abstract :
Tunable single-mode THz quantum cascade lasers are crucial for spectroscopy applications. Current and temperature tuning are limited to a few GHz and other solutions have to be implemented. Tuning by gating of the waveguide will be discussed as well as the use of external cavity set-ups.
