Left-right coupling of circularly polarized light propagating inside biaxially gyrotropic left-handed media
双轴螺旋向性负材料中极化光波的左-右旋偏振耦合

The left right coupling of circularly polarized light in biaxially gyrotropic left handed media is considered in the present paper. It is shown that this left right coupling gives rise to the frequency shifts of both left and right handed polarized light propagating inside the biaxially gyrotropic left handed media. In addition, we discuss the physical origin of left right couplings of polarized light ( i.e., the nonlocal polarization effect), and its potential applications ( e.g., controllable position dependent frequency shifts) in information science.
