N2 - We study the feasibility of dispersion compensated terahertz quantum cascade lasers combs operating around 2.65-2.95 THz to perform multiheterodyne spectroscopy. The devices show short-term intermode beat note frequency drift after 30 μs, which indicates that reliable multiheterodyne spectroscopy over extended time-scale requires phase and timing correction to allow for coherent averaging.
