Abstract

This paper presents a THz dual mode switch realized by a proper designed MEMS switchable metamaterial. The switch simultaneously controls the reflection intensity of two optical resonant modes and thus switches the ON/OFF state at two resonant frequencies. The switchable output is defined as ON state when its reflection intensity is above 65%, and OFF state if below. Furthermore, the switching between dual mode output and single mode output is also realized by suppressing one resonance mode. The proposed metamaterial dual mode switch has merits as dual mode switching and working on THz band which enable the potential applications in multi-signal control.
