Figure 1

Schematics of (a) two identical silicon ridge waveguides (width w and height h) separated from each other with an edge-to-edge distance of S; and (b) the proposed configuration that comprises a periodic silicon strip array inserted in between the silicon waveguide pair, where the inset shows an enlarged view of the strip array. The substrates and claddings for the conventional and newly proposed configurations are silica and air, respectively. The widths of the silicon strip and the air slot are w s and w a , respectively.
