Coherence and polarization of light continue to attract strong interest among the optics and physics communities. The present conference entitled Current Paths and New Horizons is the third in the Joensuu Conference Series on Coherence and Random Polarization, devoted to the electromagnetic aspects of random light. The first two conferences were arranged in 2014 and 2018 in Joensuu but the roots of the event extend even 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), both of which 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 related to the broad topic of optical coherence and polarization of random 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. The conference will be organized as an on-site event.


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

Electromagnetic coherence
Partially coherent beams: theory, formation, and shaping
Vector vortex beams and structured light
Polarization of 2D and 3D light fields
Geometric phase
Spin and orbital angular momentum
Higher-order/hybrid Poincarè spheres
Lasing and topology in plasmonic and photonics crystals
Ultrashort pulses
Interferometry and coherence metrology
Supercontinuum: fundamentals and applications
Novel imaging techniques with random light
Diffraction/optical coherence tomography
Free-electron laser/X-ray (synchrotron) coherence
Microscopy and micrometrology
Optical superresolution
Metasurface optical elements
Coherence and polarization of quantum light
Complementarity and uncertainty of quantum light
Quantum optical information
Quantum optical imaging
Quantum light sources
Classical and quantum entanglement
Electromagnetic forces and torques
Levitated optomechanical systems
Complex and time-varying media


The conference will be held at the Joensuu campus of the University of Eastern 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 currently emphasizing photonics research and technology, a thriving rock music city (Ilosaari rock in July), the Karelian marketplace, and the silence of the wilderness.
