Cogwheels for generation of surface plasmon polariton vortex
We propose a cogwheel structure formed by an air ring and equally distributed air cogs along the ring on a gold film for generation of surface plasmon polariton vortex. We show that a well-designed cogwheel can generate an optical vortex-like response and that the characteristics of such SPP vort...

| description | We propose a cogwheel structure formed by an air ring and equally
distributed air cogs along the ring on a gold film for generation of surface
plasmon polariton vortex. We show that a well-designed cogwheel can generate
an optical vortex-like response and that the characteristics of such SPP vortex
are directly related to cogwheel geometries and can be controlled by adjusting
the polarisation direction of incident light. |
