Abstract:

Lead halide perovskite is a kind of emerging new semiconductor for nanophotonics. To date, its exceptional properties have been exploited in different research areas including photovoltaics, photodetectors, and light emitting diodes etc. In this talk, I will briefly discuss the applications of lead halide perovskites on micro- & nano-lasers. Within the as-grown samples, we show different mechanisms to control the lasing modes. In addition, we have also developed top-down fabrication techniques for this material and successfully converted them from synthesized materials to various nanophotonic devices, e.g. bounded states in the continuum, color printers, meta-hologram, and nonlinear metasurfaces etc.
