Title: Dual wavelength emission from a terahertz quantum cascade laser

Abstract

We describe a heterogeneous THz quantum cascade laser that is composed of two different active region designs. This device emits simultaneously at around 2.5 THz and 2.9 THz with a certain frequency tunability by applied current. We also investigate the spectral gain in the structure by THz time-domain spectroscopy and correlate the gain spectral bandwidth with the alignment and wavelength emission behaviour of the two stack device.
