超大折射率对光子自旋霍尔效应的影响

Influence of Photonic Spin Hall Effect on Ultrahigh Refractive Index

本文研究了具有超大折射率的各向异性介质表面所发生的光子自旋霍尔效应,从理论上模拟了光自旋霍尔效应所产生的横移.结果表明,通过改变介质的折射率,我们可以很好的对此横移进行调控,横移的调控范围很大.H偏振分量的重心横移在负数到正数范围内可连续变化,V偏振分量的重心横移在此范围内不能连续变化.同时,H偏振分量的重心横移的调控范围远大于V偏振分量的重心横移的调控范围.因此,利用各向异性超大折射率介质来调控光子自旋霍尔效应对于未来的新型光子器件的诞生可以奠定良好的基础.

In this paper we have studied photonic spin hall effect at the surface of anisotropic medium with ultrahigh refractive index.We simulate the transverse displacements caused by photonic spin hall effect. The results show that we can well modulate the transverse displacements by change the refractive index of the medium and the range of the transverse displacements is very wide.The transverse displacement of H polarization component can be changed continuously in the range of negative to positive while the transverse displacement of V polarization component can＇t be changed continuously in this range.At the same time,the regulation scope of H polarization component is much greater than that of V polarization components. Therefore it is a good foundation that we modulate the photonic spin hall effect using anisotropic medium with ultrahigh refractive index for the birth of new photonic devices in the future.
