Generalized analytic formula for spin Hall effect of light: shift enhancement and interface independence

Abstract The spin Hall effect of light (SHEL) is the microscopic spin-dependent splitting at an optical interface. Whereas shift under linearly polarized well-formulated, studies on SHEL elliptically or circularly have primarily relied numerical computation. In this work, explicit analytic formula for derived arbitrarily incidence. Furthermore, from expression, we demonstrate that can be enhanced any incident angle by using polarization degree freedom and independent Fresnel coefficients interface light. will help us understand general intuitively realize unprecedented modulation SHEL.
