Optics of Excitons in Confined Systems

Dortmund, Germany
August 30th - September 3rd 2021

2nd Announcement

The Conference will be organized in a hybrid format with possibilities for both in person and online participation

Let us keep the Conference virus free! We will provide Corona test facilities.

Abstract Submission Deadline Extended

We extended the abstract submission deadline to 6th of April 2021.

About the Conference

The International Conference on Optics of Excitons in Confined Systems (OECS) will be the 17th meeting in a series with an outstanding tradition in bringing together leading scientists in the field of semiconductor optics. OECS 17 follows this tradition by covering the most recent developments in this rapidly evolving field, which involve advanced and new materials, novel experimental techniques, and recent theoretical progress. There will be no parallel sessions and the conference will provide plenty of opportunities for discussions. During the five days of the conference we plan to have 2 keynote speakers (40 min presentations), 18 invited talks (30 min duration), and about 65 contributed talks (15 min presentations).

Topics of OECS 17

  • Excitons in colloidal nanocrystals and nanoplatelets
  • Excitons in quantum wells, wires and dots
  • Excitons in perovskites
  • Excitons in emerging two-dimensional materials
  • Excitons in photonic and plasmonic structures
  • Novel polariton systems, polariton condensates, devices
  • Bose-Einstein condensation of excitons
  • Excitons in organic nanostructures and cavities
  • Spin physics of excitons and polaritons
  • Coherent and transient optical phenomena involving excitons
  • Quantum optics, single spins and excitons in nanostructures
  • Coherent control of spins and excitons
  • Nonlinear and magneto-optical spectroscopies of excitons
  • Trions, biexcitons, few-particle complexes and many-body interactions
  • Exciton-mediated optomechanics in confined systems


The conference will be held in the innogy Forum in the Dortmund U-Tower which is located in the center of the city close to the main train station. The building, constructed in 1926/27, was originally used for brewing and storing beer by the Dortmunder Union brewery. After its renovation it is used in multiple ways, for example, as museum and also Borussia Dortmund celebrated the recent championships in the Dortmunder U. It also hosts the innogy Forum which can be used as cinema or lecture hall. The hall capacity is up to 200 seats.
