Research Abstract

We have developed an electrically driven plasmon chip i.e. active plasmon modulator consisting of a metallic subwavelength grating modulated by a nano-electro-mechanical system (NEMS) type actuator. The device shifts the plasmon resonance wavelength and the transmittance when an electrical signal is applied. The same holds for plasmon waveguide. We have also developed an active gap plasmon waveguide.
