This study reports a nanoporous anodic aluminum oxide (named np-AAO) template coated with Au nanocrown array on PET substrate for photonic switching application (Fig.1). In this device, the Au nanocrown array for photonic switching are self-assembled on np-AAO/PET at its one end using batch processes. The advantages of such nano-structure photonic switches are as follows, (1) the photoconductivity of photonic switches is increased by nanostructure; and (2) the electron transport induced by localized surface plasmon resonance can be increased by the Au nanocrown array/np-AAO. (3) The np-AAO with higher flexibility and compatibility are promising nanotemplate for flexible application. In applications, flexible photonic switches consisted of Au nanocrown array on np-AAO template is implemented. Measurements demonstrate the sensitivity and photonic instant response of the nanostructure photonic switches is significantly enhanced.
