Today, bundles of optical fiber carry vast amounts of data worldwide. Our feature on the research that led to the first demonstration of low-loss fiber suitable for communications, 50 years ago, begins on p. 26.

The Breakthrough Birth of Low-Loss Fiber Optics

Jeff Hecht

Once Charles Kao had identified the promise of glass for communications, specialists in glass science took on the task of making that promise a reality. A small group at Corning succeeded by taking a contrarian approach.

Toward Intelligence in Photonic Systems

In the not-too-distant future, advances in machine learning will spur a new, transformative generation of optical communication and measurement systems.

Supreme or Unproven?

Despite much recent fanfare, quantum computers still need to show that they can do something useful.
