Nano-Photonics

Linear and nonlinear optical properties of plasmonic nanostructures

(PhD School in Physics, 3 CFU - 24 h)

Syllabus

Structure: two modules, 12 hours (4 lessons) each:

  • Module 1: Basics and linear properties (12 hours/4 lessons)
    Giovanni Mattei (giovanni.mattei@unipd.it)

  • Module 2: Nonlinear properties (12 hours/4 lessons)
    Tiziana Cesca (tiziana.cesca@unipd.it)

Abstract: Nanophotonics is the study of optical phenomena and techniques at the nanometer scale, that is, near or beyond the diffraction limit of light. It is an emerging field of study, motivated by the rapid advance of nanoscience and nanotechnology which require adequate tools and strategies for fabrication, manipulation and characterization at this scale.
This course will provide an overview of this rapidly expanding field and outline the current state-of-the-art regarding in particular the interaction of light with plasmonic nanostructures, i.e., nanometric sized building blocks made by noble metals either in form of isolated or interacting nano-objects (e.g., 1D or 2D ordered arrays). Such nanostructures behave as nanoantennas in the visible range since they are able to localize light within nanometric sub-wavelength regions. This results in the development of intense local-field hot-spots which are investigated for applications such as optical sensing, nanophotonics, optical amplifiers, nonlinear optics. The basic phenomena occurring when a laser beam is shined on the nanostructures will be presented together with the resulting linear and nonlinear optical properties.

Final Exam: Oral powerpoint presentation (20 min + Q/A time)
