Visualization2-electric field evolution in the other SERS sensor based on hybrid deep slot waveguide.mpg

The movie of |E| in the proposed SERS sensor based on hybrid deep slot waveguide which is fabricated by one-time over etching. The illumination is injected from a dielectric slot waveguide. The light transmitted in the dielectric slot waveguide is coupled into the metallic slot waveguide where the electric field would be extremely enhanced.
