Publications Calls for Papers

IEEE Photonics Technology Letters (PTL) will publish a Special Issue dedicated to presenting expanded versions of the outstanding papers from the 16th International Symposium on Measurement Technology and Intelligent Instruments (ISMTII 2025) and the 3rd International Conference of Optical Imaging and Measurement (ICOIM 2025), held from May 25-28, 2025, in Wuhan, China. ISMTII / ICOIM 2025 aims to provide a forum for world-class optical, nanometrology, precision metrology, and instrumentation experts to exchange ideas and inspire sparks. The four-day symposium will not only provide opportunities for established and early-career investigators to exchange cutting-edge techniques on measurement and instrumentation but also will bridge the gap between academia and industry by offering the opportunity to disclose the most challenging roadblocks in industry measurement and inspection. This symposium is a renowned meeting dedicated to the most recent challenges, trends, solutions, and innovations in optical imaging and measurement.

IEEE Photonics Technology Letters (PTL) will publish a Special Issue dedicated to presenting expanded versions of the invited talks from the Rank Symposium on Optical Wireless Communications in Challenging Environments, held from September 9-12, 2024, in the Lake District, UK. This symposium brought together delegates from both UK-based and international institutions to share their latest contributions to the area of optical wireless communications. Advances in solid-state light sources and photodetectors have propelled optical wireless technology to the forefront of future communications solutions. Its unique advantages—including a broad unregulated spectrum, inherent physical layer security, high transmission speeds, and resilience to electromagnetic interference—position optical wireless as an ideal candidate for meeting connectivity demands in challenging environments. Applications range from free-space communications to mining operations, healthcare, and non-terrestrial communication. Research efforts focus on enhancing the capabilities of optical wireless links to meet the key performance indicators (KPIs) for future communication networks. These KPIs extend beyond traditional metrics like data rates and latency to include crucial aspects such as security, inherent intelligence, self-adaptation, pervasive coverage, and energy efficiency

IEEE Photonics Technology Letters (PTL) will publish a Feature Section dedicated to report expanded versions of high-quality contributed and invited talks presented at the International Conference on Intelligent Computing and Wireless Optical Communications (ICWOC), held during June 21-23, 2024, in Chongqing, China. The main topic of ICWOC 2024 is Optical Wireless Communication (OWC), which is a technology that utilizes optical waves as carriers to transmit data for communication and other purposes. Owing to its advantages such as abundant and license-free optical spectrum, high transmission capacity, robustness to electromagnetic interference and inherent physical-layer security, OWC has been widely viewed as a key enabling technology for 6G. OWC reveals its great potential for many exciting applications in free-space, indoor, underwater, vehicular and satellite scenarios. Nevertheless, the practical deployment of OWC systems still faces many challenges such as bandwidth limitation, link blockage, adverse channel conditions, etc. The topics of this Special Issue include but not limited to the following: Free-Space Optical Communication, Visible Light Communication, Underwater OWC, Vehicular OWC, Satellite OWC, Visible Light Positioning, Optical Integrated Communication and Sensing, Digital Signal Processing for OWC, Machine Learning for OWC, OWC for Simultaneous Data Transmission and Energy Harvesting. Both fundamental research and application-related contributions are encouraged.
