Fig. 14.11 Numerical results of a golden pillar showing an average top roughness of 3 nm. a Mesh
resolution of the simulated structure. b Electric field distribution. The maximum field enhancement
is about 80
Fig. 14.12 Numerical results of a conical golden structure with grating coupler. a Scheme of the
device. b Electric field calculated 5 nm off the tip apex for two situations: grating and no grating.
The maximum value is found at about 30 incident angle when the grating is used. c and d electric
field distribution in proximity of the cone apex when no grating or grating is used, respectively. The
wavelength is 633 nm
