Outline of Final Research Achievements

Surface plasmons (SPs) can be efficiently excited in nanosized metal particles and structure, have a resonance wavelength depends on the conditions. Active plasmon filter consists of a metallic subwavelength grating with nano electro mechanical system (NEMS) actuator was developed the plasmon resonance wavelength to be shifted with an electrical signal. The same holds for plasmon waveguide. Therefore, the resonance wavelength and propagation distance would change in structure if the structural configuration of plasmon waveguide could be modified. This research proposes an active gap plasmon waveguide (AGPW) by forming a gap plasmon waveguide with a NEMS actuator and moving the metallic wall. When a voltage is applied to the structure, electrostatic attraction operates on the gap, deflecting the metallic walls and changing the structure. In this work, we fabricate an AGPW, and evaluate the optical characteristics with an electrical signal.
