  Optical excitation transfer in nanostructured matter has been intensively
studied in various material systems for versatile applications. Herein, we
discuss the percolation of optical excitations in randomly organized
nanostructures caused by optical near-field interactions governed by Yukawa
potential in a two-dimensional stochastic model. The model results demonstrate
the appearance of two phases of percolation of optical excitation as a function
of the localization degree of near-field interaction. Moreover, it indicates
sublinear scaling with percolation distance when the light localization is
strong. The results provide fundamental insights into optical excitation
transfer and will facilitate the design and analysis of nanoscale
signal-transfer characteristics.
