Engineered disorder and light propagation in a planar photonic glass

摘要: The interaction of light with matter strongly depends on the structure latter at wavelength scale. Ordered systems interact via collective modes, giving rise to diffraction. In contrast, completely disordered are dominated by Mie resonances individual particles and random scattering. However, less clear is transition regime in between these two extremes, where diffraction, near-field scatterers interplay. Here, we probe this transitional creating colloidal crystals controlled disorder from two-dimensional self-assembly bidisperse spheres. Choosing particle size a way that small transparent spectral region interest enables us detail effect increasing positional optical properties large With response characterized diffractive single scattering represented occurs. identify an intermediate, hopping-like transport mediated resonant interactions These results suggest different levels disorder, not only absence long range order but also differences short-range correlation interparticle distance, exist glasses.
