Nanoscale EFISH Device Schematic (IMAGE) Stanford University School of Engineering Caption This schematic shows two gold electrodes separated by a nanoslit filled with a nonlinear material. Nanoscale grating on either side of the slit directs plasmonic waves toward the slit intensifying the light field by 80 times. A small voltage is applied to the electrodes producing a massive electrical field across the narrow slit producing an EFISH light source.
