Abstract
Photonic waveguides with deterministic aperiodic corrugations offer rich spectral characteristics under surface-normal illumination. The finite-element method (FEM), the finite-difference time-domain (FDTD) method and a rigorous coupled wave algorithm (RCWA) are compared for computing the near-field and far-field properties of structures based on a Rudin-Shapiro binary sequence. All simulation methods predict multiple resonances with sensitivities in the range of 30 nm/RIU to 60 nm/RIU for bulk refractive index measurements. Local functionalization is estimated to improve the sensitivity for biomolecular binding by a factor of 2.97.
