Photonics: Promising Developments Point to Bright Future

By Dick Weisinger

The area of photonics first began in the 1960’s with the invention of lasers and was followed in the 1980’s by the development of fiber-optic data transmission. Since then, photonics has grown to a $300 billion market globally, and Precedence Research estimates that the photonics market will grow to $1.5 trillion by 2030.

Because the speed of light beats the speed of flowing electrons, photonics has the potential to upend many of our existing hardware devices. We may need to rethink our entire use of the word ‘electronics’.

Peter Delfyett, professor at the university of central Florida, said that “photonics is an enabling technology — it’s not just powering the internet but influencing the whole spectrum of scientific discovery and advancement.”

Bob Violino, technology writer, writing in LaserFocus World, said that “photonics will play a key role in the future development of Industry 4.0, because it helps foster improvements in fiber optics, additive manufacturing, IIoT, 5G, and quantum communication.”

Eyal Cohen, CEO of Chloe, writing for EETimes, said that the “high motivation to solve the painful limitations of current AI infrastructure has propelled the young photonics computing industry onto an accelerated path with large investments, large promises, and hopefully large advancements. Today, several technologies are competing for the holy grail: silicon photonics, photonics integrated circuits, glass-based photonics chips, and fiber-based photonics devices… Today’s trend of reducing carbon footprints collides with the growing AI models. Pure photonics seems to be the only large-scale sustainable solution to reconcile these trends.”
