Nanostructured dielectric waveguides are of high interest for biosensing applications, light emitting devices as well as solar cells. Multiperiodic and aperiodic nanostructures allow for custom-designed spectral properties as well as near-field characteristics with localized modes [1-4]. Here, a comparison of experimental results and simulation results obtained with different simulation methods is presented. We fabricated and characterized multiperiodic nanostructured dielectric waveguides with two, three, and four compound grating periods as well as aperiodic nanostructured waveguides based on Rudin-Shapiro, Fibonacci, and Thue-Morse binary sequences. The near-field and far-field properties are calculated employing the finite-element method (FEM), the finite- difference time-domain (FDTD) method as well as a rigorous coupled wave algorithm (RCWA).
