This conference will be devoted to the fundamental and technological issues relevant to the realization of a new generation of opto-electronic devices based on advanced low-dimensional and photonic structures, such as low threshold polariton lasers, new optical switches, single photon emitters, photonic band-gap structures, etc. It should review recent achievements in the fundamental understanding of strong light-matter coupling, as well as follow progress in the development of epitaxial and processing technologies of wide gap semiconductor and organic nanostructures and microcavities providing the basis for advanced optical studies. The conference will be open to new emerging field as carbon nanotubes and quantum information.
