Hybrid perovskite semiconductor lasers

Metal halide perovskites have emerged as promising gain media with the potential to realize wavelength-tunable, non-epitaxial laser diodes. This talk will focus on recent progress toward this goal, including continuous-wave optically-pumped lasing from methylammonium lead iodide (MAPbI3), the operation of MAPbI3 LEDs at ~kA/cm2 current densities, distributed feedback MAPbI3 LEDs that lase under optical pumping, and a new perovskite laser diode architecture that can be fabricated on silicon in a single, back-end solution processing step.
