a Sketch of the strip-loaded horizontal slot waveguide platform and the two main nanostructures studied in this article, i.e., rounded corrugations on the side wall of the polymer loading strip and a row of circular holes. b Top view and parameters of the two geometries. c Comparison of the quasi-TM fundamental mode profile (Ey) in the case of a silicon nitride ridge waveguide (blue curve) and a strip-loaded slot waveguide (red curve)
