Plasmonic Transmission Gratings – Fabrication and Characterization
Abstract
Surface plasmon polaritons (SPPs) are collective electron oscillations,<br/>confined at metal-dielectric interfaces. Coupling incident photons to SPPs<br/>may lead to spectrally broad field enhancement and confinement below the<br/>diffraction limit [1]. This phenomenon facilitates various applications,<br/>including highly sensitive refractive index sensing [2], and plasmonic dipole<br/>mirrors for cold atoms [3]. Key to a successful application is a strong<br/>photon-to-SPP coupling. To this end, prism-based coupling is classically<br/>used, but this method contradicts compact device applications. An alternative<br/>realization is given by the use of a metallic diffraction grating, where the<br/>diffracted light couples to the SPP.<br/>Here, we propose metallic periodic transmission gratings, processed onto a<br/>glass substrate, with various periods and fill factors. The gratings are<br/>milled in a plain gold layer with a focused ion beam (FIB) microscope, using<br/>gallium and a neutralizing electron beam. We investigate the SPP coupling<br/>strength with respect to varying top layers and under collimated,<br/>oblique-angled excitation, with respect to the effect of finite gratings as<br/>opposed to perfect periodicity. We characterize the proposed plasmonic<br/>transmission gratings via near-field optical scanning microscopy (NSOM) and<br/>goniometric far field measurements. We support the evidence of our analyses<br/>with numerical calculations, carried out via rigorous coupled wave analysis<br/>(RCWA) and finite-difference in time-domain (FDTD) Simulations.<br/><br/>[1] W.
