文摘

This paper presents computational analysis on higher order optical vortex lattices. Tunability of higher order topological charge can be done by tuning the predetermined phase of phase engineered beams. Simultaneously we report the symmetrical annular intensity profile around the higher order topological charge. It is also presented that generated topological rings around the higher order topological charge used in trapping of low index particle varies with topological charge at the center of vortex lattice. Laguerre–Gaussian modes are also defined using the interference method.
