When people make a video call, stream a movie, send an email, or browse the internet, few consider the technology that carries information across continents in a fraction of a second. Even fewer realize that one of the key pioneers behind this transformation was an Indian-born scientist whose work changed the course of modern communication.
The Father of Fiber Optics
That scientist was Narinder Singh Kapany, often remembered as the "Father of Fiber Optics." His groundbreaking research laid the foundation for the global communications network that powers today's digital world. Born on October 31, 1926, in Moga, Punjab, Kapany's journey began far from the laboratories where he would later make history. Raised in a Sikh family, he completed his schooling in Dehradun before graduating from Agra University. His early interest in science led him to pursue advanced studies in optics, a field that would define his life's work.
From Punjab to a Breakthrough
In the early 1950s, Kapany moved to London and joined Imperial College London. There, working with physicist Harold Hopkins, he experimented with transmitting light through bundles of thin glass fibers. At the time, scientists had explored sending images through optical fibers, but results were poor and unreliable. Kapany and Hopkins succeeded in dramatically improving image transmission through large bundles of optical fibers, a breakthrough that opened the door to an entirely new field of research. This achievement, though technical and limited at the time, proved enormous in impact. The technology evolved into fiber-optic communication systems that now carry vast amounts of data across oceans and continents.
Kapany did more than advance the science; he gave the field its identity. In 1960, he coined and popularized the term "fiber optics" through an article in Scientific American. He later wrote the first book dedicated to the subject and became one of its strongest advocates. Through his research, publications, and public engagement, he helped turn a promising scientific concept into a global technological movement.
Beyond Fiber Optics: Scientist, Entrepreneur, and Cultural Patron
Kapany's scientific interests extended well beyond fiber optics. Over his career, he worked on lasers, biomedical instruments, solar energy, and pollution monitoring technologies. His innovative thinking resulted in more than 120 patents, reflecting a lifetime devoted to solving practical problems through science. Kapany was not only a researcher but also a successful entrepreneur. In 1960, he founded Optics Technology Inc., a company focused on developing optical technologies. He later established several other ventures, bridging the gap between laboratory discoveries and commercial applications. Long before innovation and startups became buzzwords, Kapany demonstrated how scientific ideas could be transformed into products and industries.
His influence also reached academia. He taught and guided research at the University of California, Berkeley and the University of California, Santa Cruz. At Santa Cruz, he founded the Center for Innovation and Entrepreneurial Development, encouraging students and researchers to think beyond conventional academic boundaries. Yet Kapany's legacy cannot be measured only through laboratories, patents, or businesses. Deeply connected to his cultural roots, he became a passionate supporter of Sikh history, art, and education. As founding chairman of the Sikh Foundation, he spent decades supporting projects aimed at preserving Sikh culture. He donated generously to museums and universities, helping establish academic chairs and art collections that continue to educate future generations. His collection of Sikh art gained international recognition and played a major role in bringing Sikh heritage to global audiences through exhibitions in London, San Francisco, Toronto, and other cities.
Recognition and Legacy
Despite the immense impact of his work, Kapany remained relatively unknown outside scientific circles for many years. Yet the world gradually recognized the scale of his contribution. In 1999, Fortune magazine named him among the seven "Unsung Heroes of the 20th Century" for helping shape modern life through innovation. The same year, Time magazine included him among the century's leading scientists. India honored him posthumously in 2021 with the Padma Vibhushan, the country's second-highest civilian award. The recognition came months after his death on December 4, 2020, at the age of 94.
Today, every high-speed internet connection, every international data transfer, and every digital communication network carries traces of the vision that Kapany helped create. His work transformed light into information and information into a force that connects billions of people around the world. In many ways, the modern digital age travels through the path he illuminated decades ago. Narinder Kapany's story is not just the story of a scientist. It is the story of a man who looked at a beam of light and saw the future.
