In a collaboration, researchers at MPL in Erlangen, the leibnizuniversityhannover and the leibniz_ipht in Jena have developed a new type of optical fiber by freezing liquid core optical fibers (LiCOF) in nitrogen at -196 °C, leading to a phase change in the fiber core from liquid to solid.

The new type of fiber guides light and sound waves simultaneously and enables highly efficient coupling between them. The high coupling strength lowers the energy consumption of photonic neuromorphic computing schemes and quantum signal processing applications by several orders of magnitude.

“By freezing the liquid core, we have created an entirely new physical platform that provides extreme nonlinearities while being easy to handle,” says Birgit Stiller, one of the project leaders.
