Mode Modulation: Realization of Perovskite‐Nanowire‐Based Plasmonic Lasers Capable of Mode Modulation (Laser Photonics Rev. 13(7)/2019). Issue 7 (8th July 2019) - Ren, Kuankuan
Abstract : In article number1800306, Zhijie Wang, Peng Jin, Shengchun Qu, and co‐workers construct plasmonic lasers based on the structure of metal/dielectric layer/perovskite nanowires via an electrochemically assisted growth method for the high‐quality perovskite nanowires. The plasmonic lasers demonstrate a threshold of 62 µJ cm −2, a high quality factor of Q = 655, and a fast lasing decay time of 1.6 ps. The purple light represents the pumping input energy; the green‐light emission of the plasmonic laser is mainly constrained to the dielectric layer; the variations of the green spectra indicate the possibility of mode modulation of perovskite‐nanowire‐based plasmonic lasers.
