Area of Science:

  • Optoelectronics and Photonics
  • Materials Science
  • Quantum Optics

Background:

  • Solution-processed semiconductor lasers are crucial for scalable, biocompatible, and integrated photonics.
  • A significant challenge remains in matching their performance and cost to established III-V laser technologies.
  • Perovskite materials offer potential for novel laser functionalities due to their unique optical properties.

Purpose of the Study:

  • To demonstrate room-temperature continuous-wave (RT-CW) perovskite polariton lasers.
  • To achieve ultra-low lasing thresholds competitive with or exceeding state-of-the-art semiconductor lasers.
  • To explore the potential for on-chip integration and low-energy consumption light sources.

Main Methods:

  • Fabrication of a variable single-crystal perovskite microcavity.
  • Observation and characterization of room-temperature continuous-wave lasing.
  • Investigation of steady-state exciton-polariton condensation near the degeneracy point.

Main Results:

  • Demonstrated RT-CW perovskite polariton lasers with a remarkably low threshold of ~0.4 W cm-2.
  • Achieved thresholds approximately 30 times lower than state-of-the-art III-V lasers under optical pumping.
  • Successfully demonstrated indirect injection using a gallium nitride light-emitting diode (GaN LED) for initial laser chip operation.

Conclusions:

  • Steady-state exciton-polariton condensation is key to achieving ultra-low thresholds in perovskite lasers.
  • Fine-tuning cavity parameters enables strong light-matter interactions and efficient lasing.
  • This work paves the way for integrated, ultra-low power consumption perovskite lasers for advanced photonic applications.
