All-optical switching of holographic gratings made of polymer-liquid-crystal-polymer slices containing azo-compounds
Luciano De Sio, Alessandro Veltri, Cesare Umeton, Svetlana Serak, and Nelson Tabiryan
We present the observation of an all-optical switching effect that takes place when a light beam of suitable wavelength irradiates a layered structure made of polymer slices alternated to films of well aligned liquid crystal (LC) which contain also a small percentage of azo-LC molecules. The simple ... [Appl. Phys. Lett. 93, 181115 (2008)] published Fri Nov 7, 2008.
