The mid-infrared (3< λ< 5 μm) and far-infrared (8< λ< 14 μm) spectral regions are presented as a viable, yet underutilized spectral region that would be suitable for multiple WDM communication applications. Historically limited by the laser source, the quantum cascade laser, thanks to recent advances in performance, is proposed as a realistic source for addressing this spectral region. The current status of the laser technology is reviewed, as well the future outlook for this technology for WDM communication.
