title = "A compact four-wavelength quantum cascade laser source",
abstract = "A four-wavelength Quantum Cascade (QC) laser source that operates by using a single current channel is presented. The source includes two different heterogeneous QC lasers in two different waveguides, one with emission wavelengths of 7.0 μm/11.2 μm and the other with 8.7 μm /12.0 μm. Quantum Casacade lasers with emission wavelengths of 8.7 μm, 11.2 μm and 12.0 μm have threshold current densities within around 15\% of each other which allows them to be conveniently driven by a single current source.",
