2nd Joensuu Conference on Coherence and Random Polarization

Trends in Electromagnetic Coherence

June 12–15, 2018, Joensuu, Finland



Partial coherence and partial polarization of light continue to attract strong interest among the optics and physics communities. The present conference entitled, Trends in Electromagnetic Coherence, is the second in the series of Joensuu Conferences on Coherence and Random Polarization, devoted to the electromagnetic aspects of random light. The first part, Electromagnetic Optics with Random Light, was arranged in 2014 in Joensuu. The roots of the event however go farther. The series can be viewed as a successor of the ICO Topical Meeting on Polarization Optics (Polvijärvi, 2003) and Koli Workshop on Partial Electromagnetic Coherence and Polarization (Koli, 2009), that both were organized in the Joensuu area.

The main purpose of the conference is to gather again the leading scientists around the world to present their newest results on the broad topic of partial electromagnetic coherence and polarization of light. In addition to the scientifically appealing program, we expect to have lively discussions on the conference topics during the social programs.

Oral presentations are by invitation and contributed papers are accepted as posters. Only a limited number of submissions can be accepted as the conference hall is limited to 80 participants.



The conference topics include, but are not limited to, the following areas:

Electromagnetic coherence
Partially coherent beams: theory, formation, and shaping
Light propagation in random media
Coherence and polarization of ultrafast pulses
Polarization phenomena and polarimetry
Laser coherence
Interferometry and coherence metrology
Supercontinuum: fundamentals and applications
Free-electron laser/X-ray (synchrotron) coherence
Temporal and ghost/correlation imaging
Microscopy and micrometrology
Diffraction/optical coherence tomography
Information optics
Nano optics/near field optics
Plasmonics & metamaterials
Quantum optics & information
Optical coherence in nanostructures
Novel imaging techniques with random light
Coherence and polarization of quantum light
Classical and quantum entanglement

The conference will be held at the campus of the University of Eastern Finland in Joensuu, Finland. 

Joensuu is a vibrant and growing regional center which has a great deal to offer: the Karelian lifestyle, a city center with a multiplicity of services, and the Pielisjoki River flowing through it with its many possibilities. The urban lifestyle and quiet rural areas live side by side in Joensuu. All at once Joensuu is a high-tech center, a thriving rock music city (Ilosaari rock in July), the Karelian marketplace, and the silence of the wilderness, all along the border.
