Demultiplexing of optical channels based on the effect of light scattering

A numerical simulation of the scattering indicatrix of optical spectral-selective cylindrical form elements has been conducted. As follows from the results of the calculations, the shape of the scattering indicatrix of optical spectral-selective cylindrical form elements is unambiguously determined by the refractive index of the material from which they are made. Is noted the dependence of the angular position of indicatrix peaks from the light wavelength. It allows creating demultiplexers of optical channels.
