Image of FIG. 1.
FIG. 1.

Schematic of experimental setup. BS: beam-splitter; HW: half-wave plate; and P: polarizer.

Image of FIG. 2.
FIG. 2.

Fourier plane images of the reflected radial polarized 780 nm laser beam before (a), after irradiation of the linear polarized 532 nm laser (b), and subsequently irradiation of unpolarized light source (c). Inset graph on (b) shows the polarization direction of pump beam. (d) Magnified images of the part labeled with blue box shown in (b); the red lines were fixed and used to mark the original position of the SPPs ring before irradiation.

FIG. 3.

Thicker azo-polymer film; (a) Fourier plane images of the reflected radial polarized 780 nm laser beam after irradiation of the linearly polarized 532 nm laser and (b) magnified images of the part marked with blue box shown in (a).

Image of FIG. 4.
FIG. 4.

Calculated two-dimensional distribution of for a highly focused linear polarized 532 nm laser; [(a) and (b)] transversal component and , (c) longitudinal component , (d) total filed distribution ; and inset graph on (d) shows the polarization direction.
