PhotoniX Prize:Recognizing Young Achievers in Photonics
We are thrilled to announce the establishment of an esteemed award at the upcoming QPhotoniX 2023—a prize that aims to acknowledge and motivate the exceptional contributions made by young scientists who are under 35 years old in the field of photonics and its interdisciplinary applications. The initiative seeks to celebrate the visionary work of individuals who have demonstrated outstanding achievements, irrespective of age or specialization, and have significantly advanced the frontiers of photonics.
The PhotoniX Prize stands as a beacon of recognition for the young researchers who have harnessed the power of light to unlock new possibilities and drive innovation. This prestigious award draws inspiration from the renowned Fresnel Prize and embodies a similar spirit of honoring brilliance in the field of optics.
This year, the PhotoniX Prize will be awarded in two distinct categories: Frontier Exploration and Technological Breakthrough, each representing vital aspects of photonics research.
The Frontier Exploration category recognizes those visionary minds who have ventured into uncharted territories and pushed the boundaries of knowledge in fundamental photonics. This award celebrates the intellectual curiosity and courage required to embark on groundbreaking scientific quests.
The Technological Breakthrough category applauds young trailblazers who have transformed their innovative ideas into practical applications and technologies with real-world impact. This award acknowledges the transformative power of photonics in driving technological progress and societal benefits.
The PhotoniX Prize aims to inspire young researchers to continue their relentless pursuit of excellence, serving as a catalyst for further discoveries and advancements in photonics. By acknowledging their remarkable achievements, we hope to nurture and empower the next generation of photonics leaders.

According to the needs of various enterprises, the organizing committee can carry out customized personalized docking service activities.

PhotoniX Editor-in-Chief meeting:
The Editorial office of PhotoniX will invite the chief editors and editors of the journal to meet with young scholars and authors in the field of quantum photonics face to face, discuss the technical development and hot issues in the field of quantum photonics, and give guidance and answer questions on the writing, submission and evaluation criteria of international high-quality journal papers.

Pursuing Dreams Jinhua - Overseas Young Scholars Forum:
The forum is aimed at Chinese researchers studying and working overseas who are engaged in quantum photonics and related technologies. The forum is mainly a summary and presentation of all the scientific research work of researchers overseas, highlighting the highlights of work innovation in recent years. It aims to provide a good display platform for outstanding overseas scientific researchers in the subdivision field of quantum photonics, and promote the exchange and accurate docking between domestic universities, research institutes, enterprises and institutions and overseas scientific research talents.
