Dual wavelength emission from a terahertz quantum cascade laser
Joshua R. Freeman, Julien Madeo, Anthony Brewer, Sukhdeep Dhillon, Owen P. Marshall et al.
We describe a heterogeneous terahertz (THz) quantum cascade laser that is composed of two different active region designs. This device emits simultaneously at around 2.5 and 2.9 THz with certain frequency tunability by applied current. We also investigate the spectral gain in the structure by THz ti ... [Appl. Phys.
