The conference PR'19, Photorefractive Photonics and beyond, is the 17th in a series of biennial Topical Meetings that started in Los Angeles (USA) in 1987. The venue of the 2019 conference will be the city of Gérardmer in the hearth of the Vosges mountains. It will be the third conference of this series that takes place in France, after 1990 (Aussois) and 2003 (La Colle sur Loup).

In the last few editions, the scope of Photorefractive Photonics conference has been extended beyond the traditional fields of Photorefractive Effects, Materials and Devices to include topics linked to several related phenomena, the link being in connection with the nonlinear materials being used, the approaches being taken, or the kind of applications being envisaged.

The topics of interest for the PR'19 conference will include experimental and theoretical studies on:

Materials: Inorganic, organic and hybrid materials for photorefraction and nonlinear optics. Crystals, liquid crystals, polymers, nonlinear fibers, gain media.

Material micro- and nano-engineering: Ferroelectric domain engineering, waveguides, resonators, integrated photonics, volume gratings, metasurfaces and metamaterials.

Charge generation and transport: underlying physics, polaron related effects, transport in novel photovoltaïc materials (hybrid perovskites).

Wave mixing: Interferometry, dynamic holography, optical signal processing, data storage, wavefront shaping and beam cleanup, slow and fast light, EIT-related effects.

Nonlinear light-matter interaction: ultrafast processes, beam propagation dynamics, solitons, control of light by light, frequency conversion (UV, VIS, IR, THz), optical limiting and modulation, self-organization and spatio-temporal dynamics, nonlinear plasmonics.
