作者：Xiaohui Wang , Yingxiong Song

来源：[J].Optical Engineering(IF 0.88), 2018, Vol.57 (2), pp.024105-024105SPIE

摘要：By exploiting the non-Kolmogorov model and Rytov approximation theory, a propagation model of Bessel–Gaussian vortex beams (BGVB) propagating in a subway tunnel is derived. Based on the propagation model, a model of orbital angular momentum (OAM) mode probability distributio...

Hybrid multiplexing and encoding/decoding based on the spatial coordinates and mode states of vector beams in free space

作者：Yingxiong Song , Qianwu Zhang ...

来源：[J].Optical Engineering(IF 0.88), 2018, Vol.57 (9), pp.094107-094107SPIE

摘要：Due to the characteristics of spatially inhomogeneous polarization and unlimited spatial coordinates, a concept of hybrid multiplexing and encoding/decoding based on spatial coordinates and mode states of vector beams is proposed for potentially enhancing the channel capacity and...
