Halide Perovskite Semiconductor Lasers: Materials, Cavity Design, and Low Threshold

Abstract

Solution-processable semiconductor lasers have been a long-standing challenge for next-generation displays, light sources, and communication technologies. Metal halide perovskites, which combine the advantages of inorganic and organic semiconductors, have recently emerged not only as excellent candidates for solution-processable lasers but also as potential complementary gain materials for filling the “green gap” and supplement industrial nanolasers based on classic II–VI/III–V semiconductors. Numerous perovskite lasers have been developed successfully with superior performance in terms of cost-effectiveness, low threshold, high coherence, and multicolor tunability. This mini review surveys the development, current status, and perspectives of perovskite lasers, categorized into thin film lasers, nanocrystals lasers, microlasers, and device concepts including polariton and bound-in-continuum lasers with a focus on material fundamentals, cavity design, and low-threshold devices in addition to critical issues such as mass fabrication and applications.

Design of two-dimensional halide perovskite composites for optoelectronic applications and beyond

“…Low-dimensional perovskites have also shown huge potential in the lasing field, including edge-emitting amplified spontaneous emission (ASE), vertical-cavity surface-emitting lasers (VCSELs), miniature laser, polaron laser and so on. 135 Xiong et al 136 demonstrated for the first time lasing based on the whisperinggallery-mode (WGM) optical resonant cavity with the hexagonal and triangular shapes of MAPbI 3 . Fu et al 137 used 2D perovskite (BA) 2 (MA) n-1 PbBr 3n+1 to fabricate a WGM laser using polydimethylsiloxane (PDMS) template.…”

The Electron–Hole Plasma Contributes to Both Plasmonic and Photonic Lasing from CH3NH3PbBr3 Nanowires at Room Temperature

“…[1][2][3][4] At the same time, the high fluorescence yield, high gain, and wavelength tunability make LHP an ideal materials for optoelectronics research, such as light-emitting devices and lasers. [5][6][7][8][9] Numerous reports have demonstrated lasing actions in LHP including organicinorganic hybrid perovskites [6,7,10] or all-inorganic perovskites [11][12][13] in Fabry-Perot cavity, [7,10] whisper gallery cavity, [14] or distributed feedback (DFB) cavity [15] operated on plasmonic mode, [16][17][18] photonic mode, [6,7,15,19] and even polariton mode [20,21] from low temperature to room temperature or even higher. However, the lasing mechanism in LHP is still under investigation, even though various mechanisms have been proposed to explain how lasing happens.…”
