Abstract

Using the Green’s tensor area integral equation method and reflection spectroscopy, resonant light scattering from rectangular gold nanostrips on quartz substrates fabricated with electron-beam lithography is analyzed theoretically and demonstrated experimentally. Theory and experiments are compared and found in a good agreement. Design curves presenting the scattering resonance wavelength as a function of the nanostrip width allow one, by carefully choosing the strip width and thickness, to realize the resonance at a given wavelength in a broad wavelength spectrum ranging from the visible (600nm) to the near infrared including telecommunication wavelengths (1600nm).

Normalized out-of-plane scattering cross section calculated for configurations designed to have first and second order scattering resonances at approximately the same wavelength. The two thicknesses of the fabricated samples (17 and 23 nm ) are considered. The gold nanostrips on quartz (see inset) are illuminated by a p polarized plane wave at an angle of 45 ° relative to the x axis.

Normalized out-of-plane scattering cross section for 17 nm thick gold nanostrips of different widths w on quartz. The angle of incidence is 90 ° relative to the x axis, and the incident field is p polarized.

Design curves mapping first and third order resonance wavelengths versus the strip width. Two thicknesses ( t = 17 and t = 23 nm ) are considered. The curves marked with squares (t=17 nm) and circles (t=25 nm) are for gold strips or quartz substrates, and the curves marked with x (t=17 nm) and triangles (t=23 nm) are for gold strips embedded in a homogeneous medium of quartz. The angle of incidence is 90 ° relative to the x axis.
