Abstract :
Characteristics of gold nano optical antennas in 500–900 nm are studied by FDTD method. Huge confined electric field and 4500-fold Purcell factor enhancement are obtained by surface plasmons. We find nano-ellipsoids with L/R=4 is best to enhance spontaneous emission and piecewise linearity lies between our particle length and resonant wavelength.
