Keywords: | cogwheels; surface plasmon polariton; SPP vortex; whispering gallery modes; WGMs; circular polarisation; air ring; air cogs; gold film; cogwheel design; optical vortex; cogwheel geometries; polarisation direction | Issue Date: | 2015 | Source: | Xu, Z., Tobing, L. Y. M., Zhang, D., & Zhang, D. H. (2015). Cogwheels for generation of surface plasmon polariton vortex. International Journal of Nanotechnology, 12(10/11/12), 909-. | Series/Report no.: | International Journal of Nanotechnology | Abstract: | 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. | URI: | https://hdl.handle.net/10356/81876 http://hdl.handle.net/10220/39691 |
