Multiple focal segment generation of tightly focused non diffracting transversely polarized beam with diffractive optical element
J. Environ. Nanotechnol., Volume 3, No 4 (2014) pp. 73-77
Abstract
The numerical investigation of tightly focused azimuthally polarized LG beam with modulating diffractive optical element (DOE) in the focal region of high NA lens based on the vector diffraction theory is presented in this paper. It is observed, that by controlling the angles of specially designed modulating DOE can generate multiple focal spot segment in the focal region. Such kind of subwavelength focal spot segment may find wide applications in optical traps, biological, atmospheric sciences and optical manipulation technology.
