Polarization effect and emission control in asymmetric cross-shaped slot antennas surrounded with periodic corrugations

TL;DR

This paper explores how asymmetric cross-shaped plasmonic antennas with surface corrugations can be engineered to control light polarization and directionality at the nanoscale, advancing optical antenna technology.

Contribution

It introduces a novel design of asymmetric cross-shaped antennas with surface corrugations for enhanced polarization and emission control.

Findings

Directional light transmission achieved

Polarization states can be selectively controlled

Surface corrugations improve emission properties

Abstract

I discuss progress in the development of asymmetric cross-shaped plasmonic antennas based on resonant nanoscale apertures surrounded by surface corrugations. By tailoring the aperture and the surrounding surface, we show directionality and polarization control of transmitted light.
