Edge-emitting metal halide perovskites-based 1st order distributed feedback lasers are realized and studied for the first time. The properties and performances of these devices are compared in details to those of the well-studied 2nd order DFB perovskite lasers. As expected, 1st order lasers exhibit superior properties in terms of edge emission, rendering them highly attractive for applications such as photonic integrated circuits. In addition, it is found that, unexpectedly, the threshold levels of the 1st order lasers are higher than those of the 2nd order devices. We show that this phenomenon stems from the efficiency of the optical excitation which depends on the incidence angle and the gratings period.
