We are reporting on a wavelength-controlled anomalous angular light scattering with a very high spatial angular dispersion in correspondence to a very small frequencies range.

Abstract

We are reporting on a wavelength-controlled anomalous angular light scattering with a very high spatial angular dispersion in correspondence to a very small frequencies range. Essentially, we present a device able to Y-split in-air wavelengths of a laser beam few tens of nanometers away from each other. We explain its working mechanism through Moirè-interactions between structured-light and all-dielectric matter structured by light. More precisely, we ascribe this effect to Moiré-beats between holographic patterns recorded in a material and a spatially modulated wave-front of a probe-beam with slightly different spatial frequency content.
