Random lasers from photonic crystal wings of butterfly and moth for speckle-free imaging.
Chen SW, Lu JY, Hung BY, Chiesa M, Tung PH, Lin JH, Yang TC. Chen SW, et al. Opt Express. 2021 Jan 18;29(2):2065-2076. doi: 10.1364/OE.414334. Opt Express. 2021. PMID: 33726407 Free article.
Several biological membranes have been served as scattering materials of random lasers, but few of them include natural photonic crystals. Here, we propose and demonstrate a facile approach to fabricating high-performance biological photonic crystal random lasers, w …
