Efficient Metal-Halide Perovskite Micro Disc Lasers Integrated in a Silicon Nitride Photonic Platform

Metal-halide perovskites, low-cost solution processed semiconductors, have been successfully demonstrated in various optoelectronic devices, including optically pumped continuous wave lasers [1]. Straight forward deposition by spin coating [2] makes them an interesting choice for integrated micro/nano optoelectronics.
