On-chip electrically tunable nanolasing device harnessing exciton resonances in CsPbBr3

abstract

English

Optical metasurfaces, ultrathin, nanoscale structures capable of precisely controlling light, offer compact alternatives to traditional bulky optical components. However, a major challenge remains in achieving their effective electrical tunability, which is crucial for creating active, reconfigurable devices. Traditional approaches using plasmonic or Mie resonances have been limited in this respect. Our research explores the potential of harvesting the excitonic resonances in all-inorganic metal halide perovskite CsPbBr3, since it supports room-temperature stable excitonic states and exhibits highly tunable optical properties across the visible spectrum. These attributes are making CsPbBr3 an ideal candidate for electrically tunable optical metasurfaces. We aim to demonstrate a novel on-chip nanolasing device utilizing a CsPbBr3 micro-resonator. Furthermore, by investigating the voltage-dependent behavior of exciton resonances, we seek to create a nanolaser with distinct ON/OFF states, advancing the functionality of active metasurfaces. This research has significant implications for the future of quantum communication technologies, where precise control of excitonic properties is essential.
