The optics and photonics industry is at the heart of technological advancements worldwide, and Paris stands at the forefront of this revolution. With 45% of France’s optics and photonics sector concentrated in the Paris Region, the city has solidified its position as a global leader in the field. The Optics & Photonics Hub, a key initiative within the region, plays a pivotal role in pushing forward innovation. Photonics and optics have been hailed as the technology of the 21st century. With near limitless applications across multiple industries, including healthcare, artificial intelligence, defense, and sustainability, they are transforming how industries function. France, a historic leader in optics, has just the right conditions and ecosystem of cutting-edge research institutions, industry leaders, and deep-tech startups. The sector generates approximately €15 billion annually, with a workforce of 80,000 highly skilled professionals. Even with these numbers, French photonics and optics remains under-recognized. Industry leaders argue that more visibility and investment are needed to fully harness its potential and drive France’s position further in the €525 billion global market. The Optics & Photonics Hub in Paris is on a mission to reinforce the region’s leadership and put France’s industry on the map. Its objectives are several. On one hand, promotion of research and industry is key. The hub showcases industry leaders, research platforms, and training programs to attract talent and investment. On the other hand, it supports local manufacturing through R&D initiatives that translate into market-ready solutions, enhances the competitiveness and global reach of emerging photonics firms, and links the optics industry with artificial intelligence, mobility, and healthcare to address major societal challenges. Paris is already home to world-renowned research institutions such as CNRS, INRIA, and CEA, which collaborate closely with industry giants and innovative startups. The presence of cutting-edge infrastructure and specialized platforms only further enhances the region’s status.
