特殊Smith-Purcell辐射(S-SPR)是由光栅的本征模辐射产生的,它比普通的Smith-Purcell辐射具有更高的强度。然而,在以往的研究中,光栅被视为理想导体,没有考虑表面等离子体激元(SPPs),这是非常重要的纳米尺度的光栅,特别是在光学区域。本文对考虑表面等离子体效应的纳米光栅的S-SPR进行了严格的理论研究。得到了色散关系和辐射特性,并通过仿真验证了结果。根据分析,利用纳米光栅的表面等离子体共振可以实现可调谐的光辐射,这为纳米光源的发展提供了新的前景。
The special Smith-Purcell radiation (S-SPR), which is from the radiating eigen modes of a grating, has remarkable higher intensity than the ordinary Smith-Purcell radiation. Yet in previous studies, the gratings were treated as perfect conductor without considering the surface plasmon polaritons (SPPs) which are of significance for the nano-scale gratings especially in the optical region. In present paper, the rigorous theoretical investigations on the S-SPR from a nano-grating with SPPs taken into consideration are carried out. The dispersion relations and radiation characteristics are obtained, and the results are verified by simulations. According to the analyses, the tunable light radiation can be achieved by the S-SPR from a nano-grating, which offers a new prospect for developing the nano-scale light sources.
