Title
Antenna enhanced near-field optical microscopy
Description
Optical antennas are devices that convert freely propagating optical
radiation into localized energy, and vice versa. Inspired in their radiowave
counterpart, this antennas consisting of metal nanostructures exploit the
plasmonic resonance of the material they are made of. At visible
frequencies, the electrons in the metal behave like a strongly couple
plasma, leading to an enhancement of the performance and efficiency of
photodetection, light emission and sensing.
A major aim of our group is to develop and apply new techniques for
optical imaging and spectroscopy with nanoscale spatial resolution.
During the 2 months long project hosted by the NIM summer research
program, the student will have the chance to learn and apply the
fundamentals of optics as well as to take active part in the ongoing
research projects. We propose the study of optical properties of
nanomaterials such as quantum dots, nanotubes or two dimensional
materials in combination with an optical antenna.
