OPTICAL NANOANTENNA USING SINGLE-CRYSTALLINE SILVER NANOWIRE, METHOD OF MANUFACTURING THE SAME AND OPTICAL NANOANTENNA USING SINGLE-CRYSTALLINE METAL NANOWIRE

摘要

An optical nanoantenna includes a single-crystalline silver (Ag) nanowire. The single-crystalline silver nanowire is configured to output an optical antenna radiation pattern based on incident lights. The optical antenna radiation pattern includes multilobe radiation patterns, and each multilobe radiation pattern has a plurality of lobes that are radially disposed centered on the single-crystalline silver nanowire. The incident lights are visible lights in entire visible wavelength bands. Accordingly, the optical nanoantenna according to example embodiments operates at multiple resonances in the full visible range.
