Broadband distributed feedback quantum cascade laser array using a heterogeneous cascade

We demonstrated an array of distributed feedback quantum cascade lasers covering a spectral range of 220 cm -1 . The variability in threshold current and slope efficiency is explained in terms of the position of the laser end facets.
