Low threshold and highly tunable mid-infrared lasers are demonstrated based on a bound to continuum active region. Tunable emission over more than 150 cm/sup -1/ have been achieved. Terahertz quantum cascade lasers based on a bound to continuum active regions combined with an optical phonon extraction. Operation up to 117 K is demonstrated.
