摘要

Based on vectorial diffraction theory, the interference effect of phase filter to generate multiple optical focal spot in the focal region of high numerical aperture (NA) objective lens on tightly focused transversely polarized Laguerre Gaussian beam is studied numerically. Basically the incident beam will generate a focal spot in the focal region, in order to change the focal structure, the diffractive optical element (DOE) (Phase filter) is introduced. Upon optimizing and tunning the angles of DOE the multiple focal spot in the subwavelength scale is generated in the focal region of high NA objective lens. Such kind of subwavelength focal spot segment may find wide applications in optical traps, biological application, atmospheric sciences and optical manipulation technology.
