| Research Abstract |
Photo-induced voltage is generated due to the second order optical nonlinearity in 40nm-thick semi-transparent Au film with regular array of holes or dielectrically modulated structures. Experiments on these artificial structures are performed and investigated from the view point of electromagnetic field phase in the structure. Furthermore topological insulators are considered theoretically and discussed because some analogy can be found from completely different our systems.
