Abstract

The reflection, transmission, and related Goos-Hanchen (GH) shifts of structured light are investigated by multi-wave mixing conditions in this paper. The terms absorption, dispersion, group index, and photon drag rotation of structured light are also studied by multi-wave mixing. The maximum values of group index of +/- 200 and rotary photon drag of +/- 2 micro-radian are reported in this work. Significant modifications of GH shift in reflection and transmission modes are investigated with azimuthal quantum number of structured light along with multi-wave mixing. Various crater shapes are reported in reflection and transmission modes and with their corresponding GH shifts in reflection and transmission modes. The reflection and transmission GH shifts exhibit a correlation where +ve reflection GH shift regions correspond to -ve transmitted GH shift regions, and vice versa. The maximum of +ve and -ve GH shift in reflection and transmission modes is investigated up to +/- 5 lambda. The modified GH shifts in reflection and transmission modes have significant applications in high-resolution imaging, sensing, and optical signal processing.
