Waveguide optimization. (a) Effective index of the strip-loaded waveguide as a function of the nLOF strip width for the fundamental TE\(_{00}\) and the first order TE\(_{01}\) mode. The thicknesses of both TiO\(_2\) and nLOF polymer are kept constant at 200 nm and 800 nm, respectively. (b) TE\(_{00}\) mode distributions with nLOF width of 1200 nm.
