Abstract

We report a focus shaping technique for nano patterning and optical trapping of nano particles using generalized cylindrical vector beams. Cylindrical polarized light when tightly focused with high NA lens axicon generates highly confined longitudinally polarized focal spot with large depth of focus (DOF) which founds applications in nano patterning and optical trapping of high refractive index particles. We also found by properly tuning the azimuthal component of the cylindrical vector beam, the proposed high NA lens axicon can generate a sub wavelength flat top beam which is highly useful for nano lithographic applications.
