Photonics chip allows light amplification

The ability to achieve quantum-limited amplification of optical signals contained in optical fibers is arguably among the most important technological advances that are underlying our modern information society. In optical ...

New endoscope uses bendable GRIN lens for 3D microscopy

Researchers have created a flexible needle-like endoscopic imaging probe that can acquire 3D microscopic images of tissue. The bendability is possible thanks to a new flexible graded index (GRIN) lens developed by the researchers.

Existing fiber optic cables can monitor whales

A new study demonstrates for the first time that the same undersea fiber optic cables used for internet and cable television can be repurposed to tune in to marine life at unprecedented scales, potentially transforming critical ...

How astronomers can leverage fiber nets and listen to deep space

For the first time, researchers have demonstrated that a stable frequency reference can be reliably transmitted more than 300 kilometers over a standard fiber optic telecommunications network and used to synchronize two radio ...

Researchers publish study on rare-earth garnets

Researchers in the Physics Department and Institute for Nanoscience and Engineering recently published findings that may advance the understanding of rare-earth garnets, a promising material useful as a magnetic insulator ...

Bringing the chaos in light sources under control

Noise is an issue in optical telecommunications. And findings means of controlling noise is key to physicists investigating light-emitting diodes or lasers. Now, an Italo-Iraqi team has worked on a particular type of light ...
