Topical Issues: Thematic
The European Optical Society together with EDP Sciences periodically publish online, open access topical issues on specific topics in the Journal of the EOS, JEOS-RP.
Open and Upcoming Topical Issues:

PLASMONICA Collection
PLASMONICA is affiliated to the Italian Society of Optics and Photonics (SIOF) as the Plasmonics and Nano-Optics Working Group. Its core mission is gathering the nanophotonics community in Italy as well as facilitating international scientific collaborations, personnel exchange, dissemination events (seminars and workshops), and outreach initiatives.
The European Optical Society offers to the active members of the PLASMONICA community the possibility to submit an extended article/short communication. These publications will contribute to an open-ended collection of research papers, gathering and highlighting the ongoing research of the PLASMONICA community.

Recent advances and trends on lasers and nonlinear materials and sources for near-Infrared
This Topical Issue welcomes articles reporting on recent advances in laser and nonlinear materials to address the remaining scientific and technological challenges of solid-state sources for the near infrared. Materials include bulk and structured crystals, glasses and ceramics, and fibers and waveguides. Improvements in power, efficiency, brightness, stability, wavelength coverage, pulse width, design and applications will be considered.

Nano-optoelectronics: from novel materials and nanostructures to innovative applications
This Topical Issue welcomes articles reporting on recent advances in nano-optoelectronics. Topics of interest include, but are not limited to, the epitaxy of quantum dots and nanowires; quantum well, quantum dot, and quantum-cascade lasers; vertical-cavity surface-emitting lasers; widebandgap semiconductor materials and devices; functional luminescent materials; photonic crystals and plasmonics; meta-surfaces and meta-structures; photonic integrated circuits; high-speed lasers and detectors; optical communication and interconnects; microwave photonics; and photonic devices for energy, biomedical, and environmental applications.
This publication is produced on the occasion of the international Nano-Optoelectronics Workshop (iNOW 2025), which took place in Wrocław from 21–31 July 2025.
Closed Topical Issues:

THz imaging
This Topical Issue highlights research in terahertz imaging, covering innovations in both methodology and applications. Featured works explore nondestructive stratigraphic reconstruction of multilayered materials using terahertz time-of-flight tomography, optimized active sub-terahertz scanning systems for concealed-object detection, and the characterization of far-field terahertz beam profiles generated from two-color femtosecond laser pulses.
