Abstract: A method for fabricating a nanoantenna array may include forming a resist layer on a substrate, forming a focusing layer having a dielectric microstructure array on the resist layer, diffusing light one-dimensionally in a specific direction by using a linear diffuser, forming an anisotropic pattern on the resist layer by illuminating the light diffused by the linear diffuser on the focusing layer and the resist layer, depositing a material suitable for a plasmonic resonance onto the substrate and the resist layer on which the pattern is formed, and forming a nanoantenna array on the substrate by removing the resist layer and the material deposited on the resist layer. A light diffusing angle by the linear diffuser and a size of the dielectric microstructure are determined based on an aspect ratio of the pattern to be formed.

Abstract: A localized surface plasmon resonance sensor may include a localized surface plasmon excitation layer including a chalcogenide material. The chalcogenide material may include: a first material including at least one of selenium (Se) and tellurium (Te); and a second material including at least one of germanium (Ge) and antimony (Sb). The localized surface plasmon excitation layer may be prepared by forming a thin film including the chalcogenide material and crystallizing the thin film to have a predetermined pattern by irradiating laser on the thin film.
