| Abstract: | A gold film with subwavelength nanoholes on a glass substrate was fabricated through electron beam lithography and its extraordinary
optical transmission (EOT) was characterized. By applying a liquid crystal overlayer to the gold film, its EOT can be further
enhanced by ~11% due to the refractive index matching of the dielectric media on its two sides. By controlling the alignment
of the liquid crystal molecules, a highly reversible and reproducible tuning of the transmission peak in both intensity and
position is demonstrated. |
