Shannon Entropy and Lévy Statistics for Machine Learning‐Assisted Spectral Sensing in Random Fiber Lasers With Magnetic Core–Shell Nanoscatterers

open access: yesNanophotonics, Volume 15, Issue 15, 13 August 2026.
Random laser emission was observed in a polymer optical fiber structure doped with magnetic Fe3O4@SiO2 core–shell nanoparticles. A direct relationship was demonstrated between Shannon entropy and Lévy statistics regarding intensity fluctuations in the emission modes. The analysis indicated a potential application in a proposed magnetic field and energy
