摘要：

An interface supporting plasmonic switching is prepared from a gold substrate coated with a polymer film doped with photochromic molecular switches. A reversible light-induced change in the surface plasmon polariton dispersion curve of the interface is experimentally demonstrated, evidencing reversible switching of the surface plasmon polariton group and phase velocity. The switching capabilities of the interface are furthermore successfully applied to achieve focus control of a plasmonic lens. The results imply the realization of nonvolatile and reversible plasmonic switching units providing complex functionalities based on surface plasmon refraction and group delay.
