Abstract

The launching of surface plasmons by micro-gratings of subwavelength apertures milled in a thick metal film is important for the development of surface plasmon based circuits. By comparing the near-field optical images of such surface plasmon sources with the results of a Huygens-Fresnel principle based scattering model, we show that the properties of the locally launched SP beams such as divergence or uniformity can be tuned by adjusting the shape of the micro-gratings. This allows us to propose an optimized source array well adapted for providing a narrow, collimated and uniform beam.

Fig. 1.

(Color online) (a) NFO image of the SP beam launched by a source array consisting of a square lattice of 11×11 holes. Inset: SEM image (52° tilt) of a section of the array (with period 760nm and hole diameter 220nm). The polarization direction of the illumination is indicated by the double arrow. (b) Cross-sections of the SP beam taken 10μm (dark brown) and 20μm (light orange) away from the edge of the source, as indicated by the dashed lines on the NFO image. (c), (d) Corresponding simulated SP intensity and cross-sections.

(Color online) (a) NFO image of the SP beam launched by a source array with triangular lattice and (b) corresponding simulated SP intensity. Inset: SEM image (52° tilt) of a section of the array (period is 530nm).

Fig. 3.

(Color online) Simulated SP intensity integrated on each side (x<0, x>0) of a 11×11 square source with period 760nm and illumination at 800nm as a function of the incidence angle. Resonances appear at 43° for the (0,0) mode and at 47° for the (-2,0) mode. These resonances correspond to two SP beams with opposite direction.

(Color online) (a) SEM image (52° tilt) of a convex shaped source array with the corresponding NFO image (b) and simulations taking into account the finite size of the illumination spot (c) versus uniform illumination (d). (e) SEM image (52° tilt) of a concave shaped source array with the corresponding NFO image (f) and simulation (g). Simulations have the same scale as NFO images.

(color online) (a) NFO image of the diamond shaped source array. Inset: SEM image (52° tilt) of the structure (period of the square lattice is 760nm). (b) Cross-sections of the SP beam taken 10μm (dark brown), 20μm (red), and 30μm (light, orange) away from the edge of the source. (c) And (d) are the corresponding simulated SP intensity (same scale as (a)) and cross sections. (e) Plot of the SP intensity integrated over the width of the beam as a function of the distance from the edge of the source (continuous line: experimental; dashed line: simulation).
