(a) SEM images correspondingto step (2’) in Figure 5.4. (b) Shear force topography image of the structures in(a), (256 × 256 pixel, 5 × 5 µm), recorded scanning long a direction making a 45 ◦ anglewith the x-axis. The plot shows the profile corresponding to the white dashed lineshown in the topography image. The grey dashed lines in the plot indicates the edge ofthe lateral gold layer deposited on one side of the underlying relief. A 3D representationis also reported.lateral gold stripes are indeed deposited on one side of each previously inscribed relief,clearly visible on the shear-force topography profile (b-bottom). We indicate the edgeof the gold deposition with a grey dashed line.Note that, after the gold deposition under vacuum, the photochromic film is still photoactiveand a new optical pattern can be superimposed onto the gold stripe array.For instance, by projecting a two-beam interference pattern onto the sample, rotated
