Abstract

Metasurfaces are an emerging technology that enables the control and manipulation of light beams through their interaction with nano-resonators, also called "meta-atoms". A paradigmatic example of applications of metasurfaces are the so-called metalenses. In a metalens, the meta-atoms are designed to impose a phase profile in an incident beam that imitates the profile of a bulk lens. It is thus possible to obtain flat lenses with thicknesses of the order of nanometers. One key advantage of metalenses is their easy manipulation of the phase profile, which led to the design of lenses free of spherical aberration, thus solving an age-old problem in geometric optics. Another important application of metasurfaces is in sensing, where the strong interaction of light with the meta-atoms is explored as the interrogation mechanism. The aim of this research project is to investigate novel metasurface designs for application in imaging and sensing. For the imaging application, the research will focus on the development of novel phase profiles that bring new functionalities to the metalenses, with emphasis in the relationship between resolution and field of view. For the sensing application, the project will investigate the relationship between sensitivity, quality factor and spatial resolution, aiming at the development of novel photonic designs that optimise these parameters.
