Dual-comb spectroscopy is emerging as one of the most appealing applicationsof mid-infrared frequency combs for high-resolution molecular spectroscopy, asit leverages on the unique coherence properties of frequency combs combinedwith the high sensitivities achievable by mid-infrared molecular spectroscopy.Here we present an on-chip dual-comb source based on mid-infrared quantumcascade laser frequency combs, where two frequency combs are integrated on asingle chip. Control of the combs repetition and offset frequencies is obtainedby integrating micro-heaters next to each laser. We show that a full control ofthe dual-comb system is possible, by measuring a multi-heterodyne beatingcorresponding to an optical bandwidth of 32 cm$^{-1}$ at a center frequency of1330 cm$^{-1}$ (7.52 $\mu$m), demonstrating that this device is ideal forcompact dual-comb spectroscopy systems.
