This field has been driven by the advances in electronics and nanoscience that allow the precise sculpting of materials with precision down to the nanometer level. In this thesis, light-matter interaction, i.e., controlling optical response using resonant nanoscale scatterers is shown. Light-matter interaction in Mie resonance-based on all-dielectric nanoresonators is investigated. A large-scale, cost-efficient spin-coating technique is employed to form monolayer nanospheres which act as an etch mask to form the dielectric nanoresonators. In the first part of the thesis, the coupling of light in these resonators producing low-reflectivity at optical frequencies which coincides with the numerical design simulations is demonstrated. These results show promise in the production of large-area, cost-effective, low-reflection coatings useful for nanophotonics applications. In the second part of the thesis, a metamaterial-reflector is numerically designed using these all-dielectric nanoresonators on top of a silicon-on-insulator substrate, producing high-reflectivity in the visible frequency. The fabricated metamaterial reflector results are applicable to electric and magnetic mirrors for optical and infrared wavelengths, nanoantennas, molecular spectroscopy, surface-enhanced Raman spectroscopy (SERS) and subwavelength cavities.","abstract_html":"The ability to control light fields on a spatial scale far smaller than the wavelength of light has witnessed growing interest in recent years.
