Narinder Singh Kapany was a visionary Indian scientist whose groundbreaking work in fibre optics changed the way the world communicates today. At a time when the idea seemed impossible, he explored how light could be transmitted through flexible glass fibres, laying the foundation for modern high-speed communication systems. His research proved that light could travel through glass using total internal reflection, a discovery that later became the backbone of internet cables, medical imaging tools, and laser technologies. This innovation quietly transformed industries, making fast global connectivity a reality. Despite his massive contribution, Kapany’s name is often not widely recognized compared to modern tech figures. Yet every message, video, and online connection today carries the impact of his work, making him one of the true pioneers of the digital age.
