Visualization1-electric field evolution in the SERS sensor based on hybrid deep slot waveguide.mpg LiShiyu XiaLi ChenXin yangzhao LiWei 2019 The movie of |E| in the proposed SERS sensor based on hybrid deep slot waveguide which is fabricated by two-times 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.
