28 September 2013Optical tweezers formed by pure phase pupil filter
The focusing properties of vector beams have attracted great attention and quickly became the
subject of extensive worldwide research due to their applications in lithography, optical storage,
microscopy, material processing, and optical trapping. Focusing properties of the radially polarized
beam and generalized cylindrical vector beams in high numerical aperture system with designed pure
phase filter are analyzed in detail by using vector Debye diffraction theory. By utilizing diffractive
optical element to partly change the polarization of vector beams, the energy density of light field in the
vicinity of focus is studied by the numerical analysis. Numerical simulation result shows that optical
bubbles can be obtained by changing the composition and polarization of the incident beams. At last,
optical tweezers are constituted by two optical bubbles around the focus.
