摘要

Abstract

Disorder is emerging as a design principle in nanophotonics

offering new ways to control light beyond the limits of periodic architectures. Hyperuniform disordered networks

positioned between order and randomness

offer a unique platform for this exploration. Using large-scale numerical simulations and hyperspectral near-field imaging

we uncover spectral level repulsion among delocalized modes – a universal signature of interacting states in complex systems

from nuclear physics to quantum chaos

experimentally observed here for the first time in correlated disordered photonics. Within the same platform

we provide a phenomenological identification of classes of localized modes in hyperuniform disordered networks: genuine Anderson states and defect-induced resonances associated with Lifshitz-like photonic states. Unlike their electronic counterparts

these Lifshitz-like states arise from architecture-encoded topological defects and can hybridize into coupled "photonic molecules". Our results reveal a potentially reconfigurable regime of disorder where localization

correlations

and coupling can be engineered

opening new opportunities for random lasing

optical filtering

and quantum photonics.
