Distributed feedback (DFB) structured QCLs that emit a continuous wave (CW), single-mode mid-infrared laser beam at room temperature. By controlling the chip’s operating temperature through the Peltier element within the laser’s package, it’s possible to tune the emission wavelength without mode hopping while keeping a longitudinal single-mode operation.
