Room-temperature nanolasers are crucial for advancing optical communication and photonic quantum technologies due to their capability to generate coherent light at a subwavelength scale. However, their development is constrained by challenges such as insufficient gain, material instability, and high lasing thresholds. A research team led by Dr. Yu-Jung Lu at the Research Center for Applied Sciences, Academia Sinica, and Dr. Chu-Chen Chueh from National Taiwan University, demonstrated a stable, wavelength-tunable, single-mode room-temperature plasmonic lasing by integrating quasi-two-dimensional (quasi-2D) perovskites with high-Q plasmonic nanostructures. The research findings provide a scalable, low-cost, and energy-efficient platform for nanolasing, with potential applications in next-generation photonic technologies, including LiDAR, sensing, optical communication, and computation. The research has been published on May 7, 2025 in Science Advances, and was featured on the journal’s homepage as a highlighted article.
