Enhanced Nano-size Circularly Polarized Light Generated by Cross V-groove Aperture Antenna
説明
In the last decade, the circularly polarized light has been widely used in various novel applications, such as probing the geometric and electromagnetic chiral properties of biomolecules [1], all-optical magnetic recording [2] and control of the spin-wave emission [3] in submicron regions. To implement those researches in nano-regions, it is essential to generate nano-size circularly polarized light. Nakagawa et al. [4] has reported that nano-size circularly polarized light could be generated with a cross aperture antenna. However, the intensity of generated circularly polarized light is not enhanced. Here, we propose a new type cross V-groove aperture antenna with a diameter of 10 nm, which could generate circularly polarized light, with its intensity enhanced more than 1000 times.
