Thumbnail image of graphical abstract

A terahertz all-optical modulator is realized by combining the surface-plasmon-related extraordinary optical transmission phenomenon of subwavelength hole arrays and the transient properties of molecules. As shown in the figure, transmission of the signal beam (red) is modulated after excitation of the hybrid structure by the pump beam (green). This modulator may lead to ultrafast all-optical active plasmonic devices.
