High-quality microwave signals generated from tiny photonic chip

In a new Nature study, Columbia Engineering researchers have built a photonic chip that is able to produce high-quality, ultra-low-noise microwave signals using only a single laser. The compact device—a chip so small, it ...

What do you do with a shrunken laser?

The laser is so small you need a microscope to see it properly. But it's not just the size that scientists at Sandia National Laboratories are excited about.

Photonics experiment resolves quantum paradox

It seems quantum mechanics and thermodynamics cannot be true simultaneously. In a new publication, UT researchers use photons in an optical chip to demonstrate how both theories can be true at the same time. They recently ...
