The proposed project aims to engineer an on-chip electrically tunable nanolasing device utilizing CsPbBr3. The nanolasing device will consist of CsPbBr3 nanostructures, harnessing their exciton resonances and effectively tuning their optical emission. This work extends the concept of utilizing excitonic resonances in flat semiconductors for nanophotonics. By demonstrating on-chip electrically driven lasing with ultralow thresholds, this interdisciplinary approach paves the way for ultrafast optical information processing.
