摘要
The movement of photosensitive azo polymers induced by scanning near-field illumination is studied. As a function of the photon flux illuminating the sample and exposure time, different effects are obtained: from a nanoscopic reorientation, inducing birefringence in the sample, to a macroscopic movement of the photosensitive polymers. It is also shown that this movement is strongly influenced by the state of incident light polarization. The combination of azo polymers and near-field illumination allows encoding sub diffraction information and can be exploited in applications as nanomachining and nanofabrication.
