Intuitively, when the light interacts with a dielectric whose size is equal to a few wavelengths, a diffusion phenomenon is observable. But in 2004, a near-field focusing, weakly divergent with the full-width at half-maximum (FWHM) that could be smaller than the wavelength is observed. So, this high-intensity beam can overtake the classical diffraction limit. This finding of considerable scientific importance has been successfully used for several applications (etching, detection, imaging, data-storage devices, ). Currently, the generation of photonic jets is mainly carried out with a free space excitation. However, some works use surface plasmon polaritons to excite a micro-scaled dielectric of different shapes . Photonic jets can also ...
