Hybridized Guided-Mode Resonances via Colloidal Plasmonic Self-Assembled Grating.
ACS Applied Materials & Interfaces 2019 March 16
For many photonic applications, it is important to confine light of specific wavelength at a certain volume of interest at low losses. So far, it is only possible to use the polarized light perpendicular to the solid grid lines to excite waveguide plasmon polaritons in a waveguide supported hybrid structure. In our work, we use a plasmonic grating fabricated by colloidal self-assembly and an ultrathin injection layer to guide the resonant modes selectively. We use gold nanoparticles self-assembled in a linear template on a titanium dioxide (TiO2) layer to study the dispersion relation with conventional UV-vis-NIR spectroscopic methods. Supported with finite-difference time-domain (FDTD) simulations we identify the optical band gaps as hybridized modes: plasmonic and photonic resonances. Compared to metallic grids, the observation range of hybridized guided-modes can now be extended to modes along the nanoparticle chain lines. With future applications in energy conversion and optical filters employing these cost-efficient and up-scalable directed self-assembly methods, we discuss also application in refractive index sensing of the particle based hybridized guided-modes.
