(Color online) (a) The reflected power as a function of data position; the effective profile of the data structure is shown as a dashed line. The solid line is the result for a plate and data surface both consisting of evaporated silver; the dashed line is for both consisting of silicon. Here, , , , , and the data structure is taken to be a pit in the data surface with . (b) Plot of the time-averaged electric energy density in the neighborhood of the slit and data structure, with the plate and surface both taken to be evaporated silver. The data have been plotted on a logarithmic scale to enhance visibility of the plasmon standing wave. Redder regions correspond to a higher-energy density. Here . To the right of the slit, alternating bright and dark regions indicate the presence of a plasmon standing wave. indicates the plasmon wavelength. The figure scale is in nanometers.

(a) Transmitted power as a function of plasmon pit location, for pits on the illuminated side of the plate. The inset shows the system configuration. (b) The reflected power as a function of data position, both with and without the plasmon pits on the illuminated side of the silver plate. Here, , , and the data surface is silicon; all other parameters are the same as in Fig. 2(a).

(a) Transmitted power as a function of plasmon pit location, for pits on the dark side of the plate. The inset shows the system configuration. (b) The reflected power as a function of data position, both with and without the plasmon pits on the dark side of the silver plate. Here, , , and the data surface is silicon; all other parameters are the same as in Fig. 2(a).
