New method makes microcombs 10 times more efficient

Microcombs can help us discover planets outside our solar system and track new diseases in our bodies. But current microcombs are inefficient and unable to reach their full potential. Now, researchers at Chalmers University ...

All-fiber ellipsometer for nanoscale dielectric coatings

Measuring the refractive index and the thickness of thin films (films with a thickness from less than a nanometer to several microns) is essential to characterize them and improve the performance of sensors and devices that ...

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 ...
