Modeling the finite-difference time-domain method (FDTD) using the software package FullWAVE focusing Gaussian beam width of 5.4 um and a wavelength of 0.633 um using a binary grating made of silica (refractive index 1.46) showed that the individual steps relief near its output surface form the focal spots - photonic nanojet. This photonic nanojet bent at the wavefront tilt.
