主 题:PT symmetry exceptional points laser mode spin Hall effect
摘 要:We proposed and demonstrated that PT symmetric metamaterials could be used to achieve enhanced spin Hall effect(SHE)of *** find that when laser mode is excited in PT symmetric system,the enhanced SHE could be obtained in both transmitted and reflected *** addition,as exceptional points(EPs)of PT symmetric system can happen for both p-and s-polarizations,the enhanced SHE of reflected light can function for both horizontally and vertically polarized incident ***,these EPs can lead to unidirectional reflectionlessness,asymmetric SHE with maximum contrast ratio of 48 is obtained by launching light beams near *** work opens up a new path to obtain enhanced transverse displacement for both reflected and transmitted light and enables more opportunities in manipulating photonic SHE.
