“…P ERIODIC nanostructures have been widely researched in the field of optics as promoters of phenomena such as light scattering and diffraction [1], [2], [3]. In integrated photonics, planar nanogratings coupled with optical waveguides exploit the diffraction phenomenon for routing portions of the guided light in and out of the optical chip [4], [5], [6], [7]. In plasmonics, light interaction with 2D metal periodic nanoarrays is used for surface plasmon resonance (SPR) and induces phenomena such as fluorescence, dichroism, and Raman scattering [8], [9], [10].…”

This paper presents the optical analysis on how the light coupling performance between optical channel waveguides and gold periodic nanoarrays in the visible spectrum can be improved using an indium tin oxide (ITO) thin film as buffer layer. Coupling efficiency, out-of-plane scattering and far-field projected beam focus and diffraction angle are evaluated using Finite-Difference Time-Domain (FDTD) method and scattering theory for different nanogratings and nanocylinders array patterns. The implementation of ITO enables up to a 12 fold increase in coupling efficiency, a 6.4 fold enhancement of light scattered out of the array plane and consequent improvements in the diffracted beam radiation intensity peaks, without compromising the beam's focus or altering its deflection angle. This configuration provides a cheap and simple solution to increase the device performance without changing the array features, for integrated biosensing and scattering-related applications.
