Abstract

We report optical writing at the nanometer scale of spin coated PMMA-spiropyran films. By using a near-field optical microscope, pure optical nano-writing with a resolution of 160 nm and writing speed of 0.4µm/s was achieved. Simultaneous topographic and optical writing was also obtained by simply coupling to the near-field few more mW of laser power. Due to the fast optical response of the spiropyran molecule, nano-lithography on PMMA-spyropyran thin films appears to be very attractive for future photonics applications.

Chemical structures of Spiropyran and Merocyanine molecules (top of the figure); the far-field absorption spectrum of Spiropyran (black line) and Merocyanine upon irradiation with violet light (dashed line).

Schematic diagram of the experimental setup for nano-writing/reading in near-field.

2µm × 2µm (a) topographic and (b) optical image of the pattern obtained by illuminating the sample at 404 nm and line profile (c) of the optical image. From (c) we evaluate an optical resolution of the writing process of 80 nm by accounting for the probe aperture size and the effects of the optical convolution.

2µm × 2µm (a) topographic and (b) optical image of the pattern at the nanoscale obtained by driving the SNOM probe over the sample surface along a squared path at a speed of 0.4 µm/sec.

Fig. 5

2µm × 2µm (a) topographic and (c) optical image of the pattern obtained by illuminating the sample at 404 nm with 2.5, 5 and 10 seconds of exposure (from the bottom upwards); line profile of the topographic (b) and optical (d) image.
