| description | Perovskite semiconductors show great promise as gain media for all-solution-processed single-mode microlasers. However, despite the recent efforts to improve their lasing performance, achieving tunable single-mode microlasers remains challenging. In this work, we address this challenge by demonstrating a tunable vertical cavity surface emitting laser (VCSEL) employing a tunable gain medium of halide phase-change perovskites-specifically MAPbI3 perovskite, sandwiched between two highly reflective mirrors composed of bottom-distributed Bragg reflectors (DBRs). This VCSEL possesses single-mode lasing emission with a low threshold of 23.5 μJ cm−2 under 160 K, attributed to strong optical confinement in the high-quality (Q) cavity. Upon the phase change of MAPbI3 perovskite, both its gain and dielectric constant changes dramatically, enabling a wide (Δλ >9 nm) and temperature-sensitive (0.30 nm K−1 rate) spectral tunability of lasing mode in the near-infrared (N-IR) region. The laser displays excellent stability, demonstrating an 80% lifetime of >2.4×107 pulses excitation. Our findings may provide a versatile platform for the next generation of tunable coherent light sources. |
