Researchers have found that under certain conditions, a laser beam can act like an opaque object and cast a shadow, opening new possibilities for technologies that could use a laser beam to control ...

Engineers are turning what used to be a bulky optics bench into something that fits on the tip of a finger, and the latest photonic chips go a step further by splitting a single laser into a ...

The invention of a nanolaser is the first step towards future digital communication, where communication on microchips can be based entirely on light particles.

The laser module is one of the least reliable components in such a system. For that reason, it remains in a convenient pluggable form, enabling easy and inexpensive replacement. If designers were to ...
