Using this setup, the images in Fig. 8.19 have been obtained. The images (a) and (b) show the same surface area, which is covered by light-emitting nanofibers, but with differently polarized excitation light. Obviously, the op-... 

It is instructive to compare the SH microscopy results with the near-field images of Fig. 9.6 which show the same kind of light-emitting nanofibers. The spatial resolution of SH microscopy is lower ( 700 nm) compared with scanning near-field optical microscopy (SNOM) the contrast ratio, however, is much better. Nevertheless, it recently also became possible to determine molecular orientations via SH-SNOM (Fig. 9.14). 

Fig. 9.14 Two-dimensional images of molecular orientations along light-emitting nanofibers, obtained from polarized TP-SNOM measurements and applying Eq. (8.10). The two images show the same aggregates with measured data obtained for sp/pp orientations and...

Light-emitting ID nanomaterials made by conjugated potymers have unique features because they combine optoelectronic properties of semiconductors with structural properties of potymers. Organic nanowires, nanofibers, and nanotubes can be produced by different techniques, including template-assisted synthesis and vacuum sublimation. However, the lowthroughput of many of these approaches limits their application in photonic integrated systems.
