Hybrid metal-dielectric metasurfaces for enhanced optical performance
Metasurfaces are periodic arrays of light scatterers or resonators. The dimensions of these resonators and the spacing between them are smaller than the incident light. Metasurfaces can manipulate the amplitude, phase, and polarisation of the incident light by controlling the resonators’ shape, …

Dynamic Metasurfaces for Advanced Applications
<p>To date metamaterials and metasurfaces have been studied for over 20 years. Throughout this time sophisticated understanding of their properties and capabilities has been developed, with many significant and exotic properties such as flat lenses, negative refraction, and perfect absorption. In …

Controlling light-matter interaction with resonant semiconductor nanostructure
This thesis aims to bridge dielectric materials' optical and electronic properties to obtain full control of light-matter interaction at the nanoscale. The outcomes may open the way for tunable, ultra-thin, cost-effective, and energy-saving optoelectronic devices. This research first studies the …
