In this article, a spiral broadband nano-antenna device is studied theoretically and experimentally. This device can produce highly intense electric fields over a wide range of wavelengths, which can be used to excite nonlinear effects such as surface enhanced Raman scattering (SERS) over a wide range of wavelengths or be used to improve the performance of solar cells. SERS enhancement factor higher than 105 can be obtained with this device.
