Figure 1: Gold bullet optical-field emitter. (a) Emitter geometry; (b) 2-D electric field amplitude map in a plane of the emitter axis. Radius of the cylinder and hemispherical tip is 5 nm. Cylinder length is 30 nm. The illumination source has a wavelength of 810 nm. Gold ( =-24.9+1.57i) and water ( =1.77) are chosen as tip and dielectric materials, respectively. The optical triggering field propagates in x-direction (from left to right) and is polarized along the y-axis (in-plane and along the tip axis). Propagation (k) and polarization (E) directions are shown as arrows. The field enhancement displayed in (b) is normalized with respect to the incident optical field and has a peak enhancement factor ~3.7 at the apex of the “bullet”.
