23_07i/2011Dichroic Optical Structures: Selective Dichroic Patterning by Nanosecond Laser Treatment of Ag Nanostripes (Adv. Mater. 7/2011)

The inside cover illustrates the fabrication process of dichroic optical patterns by nanosecond laser processing of silver-decorated, oriented SiO2 nanocolumns. Using this straightforward methodology, reported by Johann Toudert, Ana Borras, and co-workers on p. 848, it is possible to selectively tune the surface plasmon of the silver nanostripes along the visible range as a function of the laser power during the irradiation. These optical structures are of application for optical encryption and related applications.
