摘要
Using anomalous large diffusion we report a recording of reflection type gratings in a PVK-based photonrefractive polymer without any external electric field. Diffraction efficiency of the gratings was measured to be 7%. An efficient modulation of beams during two-beam coupling up to 12% was demonstrated by using phase modulation technique. This practical scheme can be used in dynamic vibration measurements.
