Description
While until recently, the emission and absorption of light were considered intrinsic properties of
atoms, molecules, or crystals, the ability to design structures at the micro- and nanometer scale
has opened new ways to control the optical properties of materials. Micro cavities or photonics
band gaps make it possible to modify the density of electromagnetic modes surrounding the
emitters and to change their coupling with that environment. Design of microstructures allows
efficient coupling of light with plasmons in metallic materials. A new field of optics is emerging from
these perspectives to control light-matter interaction.
