New technology to amplify light using air – Tech Explorist
In a promising breakthrough for the future of communications, EPFL researchers have developed a technology that can amplify light in the latest hollow-core optical fibers.
Luc Thévenaz, the head of the Fiber Optics Group in EPFLs School of Engineering, has finally made it happen. He, along with his colleagues, has developed a technology to amplify light inside the latest hollow-core optical fibers.
This new approach relies on new hollow-core optical fibers that are filled with either air or gas.
Professor Thévenaz explains, “The air means theres less attenuation so that the light can travel over a longer distance. Thats a real advantage. But in a thin substance …
