More specifically, CLEO®/Europe emphasizes applied physics, optical engineering and applications of photonics and laser technology whereas EQEC emphasizes basic research in laser physics, nonlinear optics and quantum optics.

CLEO®/Europe will showcase the latest developments in a wide range of laser and photonics areas including laser source development, materials, ultrafast science, fibre optics, nonlinear optics, terahertz sources, high-field physics, optical telecommunications, nanophotonics, biophotonics.

EQEC will feature the fundamentals of quantum optics, quantum information, atom optics, ultrafast optics, nonlinear phenomena and self-organization, plasmonics and metamaterials, fundamental nanooptics, theoretical and computational photonics.

This combination provides a unique forum to obtain informative overviews and discuss recent advances in a wide spectrum of topics, from fundamental light-matter interactions and new sources of coherent light to technology development, system engineering and applications in industry and applied science.

CLEO®/Europe-EQEC 2021 conference is Europe’s largest conference on photonics and related research fields. The program features plenary lectures, keynote and tutorial speakers, invited talks, contributed talks and poster sessions within the different topics.
