Process engineering study of photonic nanojet from highly intense to higher propagation using FDTD method

This theoretical study is mainly focused on to show the behavior of photonic nanojet from highly intense to higher propagation produce from a set of purposed droplet type microstructures. Simulation result clearly indicated that the proposed combined structure of a hemisphere and a cone of equal radius can able to produce a photonic nanojet having the intensity larger than the conventional spherical microstructure. By decreasing the height offered by the spherical part of the micro structure gives an increased zigzag type response for the propagation length which was found to be maximum for cone. However the intensity of photonic nanojet decreases with decrease in height offered by spherical part of the proposed microstructure.
