High directivity optical antenna substrates for surface enhanced Raman scattering.

Dongxing Wang¹, Wenqi Zhu, Yizhuo Chu, Kenneth B Crozier.

Abstract

A two-dimensional array of gold optical antennas integrated with a one-dimensional array of gold strips and mirrors is introduced and fabricated. The experimental results show that this design achieves average surface-enhanced Raman scattering (SERS) enhancement factors as high as 1.2 × 10(10) , which is more than two orders of magnitude larger than optical antennas without the gold strips and gold mirror.
