  • Abstract Surface plasmon resonance (SPR) is sensitive to surface structure, metal thickness or refraction index of medium layer.
    Liquid crystal is anisotropic, and optically, the refraction index of light is related to its direction and polarization.
    In this research, the birefringent nematic liquid crystal (NLC) with uniaxial crystal structure, E7, was injected to a liquid crystal cell with metallic gratings, and placed on a prism with Kretschmann structure. From the characteristics of electro-optical modulation of liquid crystal, E7 was used to serve as the switch which can couple surface plasma wave. Pumping light source was controlled to be coupled or un-coupled by changing the refraction index of liquid crystal, and SPR mode effect modulated by liquid metal would be reached.
