Inside Back Cover: Plasmonic switch based on composite interference in metallic strip waveguides (Laser Photonics Rev. 8(4)/2014)



A plasmonic switch is implemented by two crossed metal strip waveguides with a Bragg grating as the beam splitter in the crossing. Based on a newly discovered composite interference, surface plasmons from two input ports can be selectively transferred into two outputs in a controlledmanner depending on the proportion of two kinds of interferences.
