This paper introduces a metasurface interconnection method via attaching antiresonant waveguide, and proposes an inline optical transmission modulator by filling liquid crystal. Research verifies the capability of the antiresonant fiber and the good performance of the liquid crystal device.
The growth of the nanotechnology and intense studies on subwavelength nanophotonics has facilitated research in the field of metamaterials and metasurfaces. Optical waveguides has been a proper platform for metasurface applications because of its versatility and numerous infrastructure. In this paper, a metasurface interconnection method via attaching antiresonant waveguide is introduced. The antiresonant waveguide allows all-waveguide type inline metasurface schematic. Numerical calculations verified that the antiresonant fiber is capable of metasurface interconnection. In addition, an inline optical transmission modulator has been proposed by filling liquid crystal inside the hollow region. A liquid crystal device with on- state transmittance of 93.64%, and off-state transmittance of 0.96% with a smooth transient region are achieved.
