Tunable quantum cascade lasers operating in the terahertz frequency range are demonstrated. By using an external cavity based on the reflection from a movable mirror, both broad and fine tuning of the frequency are achieved by varying the cavity length. Coarse tuning up to 3 cm-1 is obtained near the center frequency of 4.8 THz (∼160 cm-1), and continuous mode-hop-free tuning is observed over ∼ 0.4 cm-1, nearly corresponding to the cavity free spectral range.

Abstract

Tunable quantum cascade lasers operating in the terahertz frequency range are demonstrated. By using an external cavity based on the reflection from a movable mirror, both broad and fine tuning of the frequency are achieved by varying the cavity length. Coarse tuning up to 3 cm-1 is obtained near the center frequency of 4.8 THz (∼160 cm-1), and continuous mode-hop-free tuning is observed over ∼ 0.4 cm-1, nearly corresponding to the cavity free spectral range.
