Title: Effect of numerical aperature on the spectral splitting feature near phase singularities of focused waves
Author(s): Ganic, Djenan; Chon, James W. M.; Gu, Min
Abstract: We demonstrate that because of the depolarization effect associated with a high-numerical-aperture lens, the recently predicted spectral splitting phenomenon near phase singularities of focused waves [G. Gbur, T. D. Visser, and E. Wolf, Phys. Rev. Lett. 88, 013901 (2002)] disappears when the numerical aperture is higher than critical values that are different between the incident polarization direction and the axial direction.
