Shaping light at the nanoscale with dielectric nanoantennas
In the last decade, nanophotonics has emerged as one of the most important research fields in optics. A tiny nano-object plays the role of a nanoantenna, when excited by a light source, it scatters light in the surrounding environment in one or more directions that depend on its geometry and material. An important issue that has not been fully understood yet is how to control the directionality and power of this scattered radiation.
The scope of this PhD project is to advance our knowledge in nanophotonics by designing and fabricating nanoantennas that allow full control of the scattered field at the nanoscale. Single nanoantennas with arbitrary shape as well as arrays of coupled nanoantennas will be designed, fabricated and tested.
