Abstract

An erratum is presented to clarify both the direction of light polarization in our experiments and the unit cell geometry of the samples. Additionally, the spectral dependence of the second harmonic generation response in the G-shaped nanostructures made of gold is corrected. These changes do not affect our previous conclusions.

Schematic diagram of the sample geometry of the G-shaped and of the mirror-G shaped sample structures, in (a) and (b) respectively. In (c) and (d), the SHG microscopy images of the G-shaped and of the mirror-G shaped sample structures respectively. The white arrows indicate the direction of the linear polarization. The color coded intensities increase from purple, through green, then yellow to red.

Fig. 3

In (a), (b), (c) and (d), schematic diagram of the sample geometry of the mirror-G shaped sample structures rotated in steps of 90°. In (e), (f), (g) and (h), the corresponding SHG microscopy images. The color coded intensities increase from purple, through green, then yellow to red. The red squares emphasize the pattern reproducing the mirror-G unit cell in Fig. 1. The white arrows indicate the direction of the linear polarization, which is identical for all images shown.

Fig. 4
Fig. 4

In (a) to (f) SHG microscopy images of the G-shaped sample structures as function of increasing fundamental wavelength from 750 nm to 1000 nm in steps of 50 nm. The color coded intensities increase from purple, through green, then yellow to red. The white arrows indicate the direction of the linear polarization. In (c), a unit cell is superimposed on the pattern to illustrate the location of the hotpots. The laser powers were measured on the microscope stage, upon focusing with the objective.
