Abstract: Integration of multiwavelength distributed feedback quantum cascade lasers (QCLs) in C-mount packages is demonstrated in this paper, which is applicable to portable gas sensors. The thermal management is performed by modeling and experimentally verifying. The QCLs with the wavelength of 4492, 5459, 6224, and 9640 nm are integrated. The wavelength tuning range and optical power of each QCL are no smaller than 6.5 nm and 65 mW, respectively. The dimensions of the integrated sources are 40 mmx40 mmx80 mm $40\unicode{x0200A}\text{mm}\times 40\unicode{x0200A}\text{mm}\times 80\unicode{x0200A}\text{mm}$.
