International Study Reveals Exceptional Property of Next Generation Optical Fibres
Written by AZoOpticsFeb 16 2021
Researchers from the University of Southampton and Université Laval, Canada, have successfully measured for the first time back-reflection in cutting-edge hollow-core fibres that is around 10,000 times lower than conventional optical fibres.

This discovery, published this week in The Optical Society’s flagship Optica journal, highlights yet another optical property in which hollow-core fibres are capable of outperforming standard optical fibres.
Research into improved optical fibres is key to enable progress in numerous photonic applications. Most notably, these would improve Internet performance that heavily relies on optical fibres for data transmission where

In Paris. Exactly Seventy Years Ago.
He likely arrived in Paris from Darmstadt, Germany, by train that January, exactly seventy years ago. At 53, and a full professor of applied mathematics and the founding director of the Institut für Praktische Mathematik at the Technische Hochschule Darmstadt, Alwin Walther was among Germany’s leading figures in computation. The calculational prowess of Walther and his Institut–employing all manner of manual, mechanical, and electromechanical approaches–had attracted the attention, and the support, of the Nazi regime during the Second World War. But as Walther made his way to the academic heart of liberated Paris, the Latin Quarter, few passersby would have guessed at this background.

A global team of engineers from the UK, US, and China has developed a breakthrough sensor system and manufacturing process to produce ultra-thin smart contact lenses.
The engineers from the University of Surrey – together with partners from Harvard University, University of Science and Technology of China, UK National Physical Laboratory, George Washington University and Zhejiang University Ningbo Research Institute – say their system can be directly incorporated onto soft contact lenses using an easy assembly method. The final design will provide comfort and biocompatibility, robustness, transparency, and detection sensitivity, which outperforms other smart lenses.
Dr Yunlong Zhao, the study’s corresponding author, said devices such as theirs could be used as a
Surrey Unveils Breakthrough Manufacturing Process of Ultra-Thin Sensor for Smart Contact Lenses
In a paper published by the journal Matter, engineers from the University of Surrey together with partners from Harvard University, University of Science and Technology of China, UK National Physical Laboratory, George Washington University and Zhejiang University Ningbo Research Institute report on how they have developed a breakthrough sensor system and manufacturing process.
The global team of engineers reveal that the new contact lens sensor system contains a photodetector for receiving optical information, a temperature sensor for diagnosing potential corneal disease and a glucose sensor for directly monitoring the glucose levels in tear fluid.
