Can a Quantum Network “Hacker Proof” Fiber Optic Cables?

Leave a Comment

In 2013, Edward Snowden, a U.S. National Security Agency contractor, leaked documents showing that intelligence agencies were spying on the data of private citizens. One disturbing fact was that the spies tapped into optical fiber cables to access the huge amount of data moving through these cables.   Snowden’s disclosures pushed researchers to use quantum science […]

Smaller Endoscopes from New, Air-Filled Optical Fiber Bundles?

Leave a Comment

A new, air-filled optical fiber bundle could dramatically improve medical endoscopes. This technology could also help create endoscopes that produce images using infrared wavelengths. If so, this breakthrough would allow diagnostic procedures that aren’t currently possible.   In the Optical Society (OSA) journal Optics Letters, University of Bath (U.K.) researchers showed that these new fiber […]

Could Fiber Optic Sensors Help Prevent Power Theft?

Leave a Comment

Fiber optic sensors could one day catch thieves who steal electricity and materials from overhead power lines. The UK firm Bandweaver recently demonstrated a distributed acoustic sensing (DAS) system that detects invasion and interruption on power lines. The system does this by using back-scattering effects along an optical fiber.   The Cost of Tampering A […]

New Fiber Optic Gyroscope: More Precise, Smaller than a Grain of Rice

Leave a Comment

Engineers at the California Institute of Technology have created the world’s smallest fiber optic gyroscope. Five hundred times smaller than a regular gyroscope, this new gyro can fit on a grain of rice. This research breakthrough could lead to more accurate fiber optic gyros compared to mechanical units.   WHAT OPTICAL GYROS DO Advanced fiber […]

Make Way for High-Density Fiber Optic Cables

Leave a Comment

More fiber density in less space. From 5G to data centers to FTTx, the picture is clear. Everyone uses more bandwidth than ever before. And while bandwidth demand may seem endless, the space to install fiber optic cable isn’t. That’s why being able to install more optical fiber in the same or less space can […]

Optical Fiber “Senses” Surroundings

Leave a Comment

Companies use optical fiber as a sensor to detect changes in temperature and pressure. This technique is often used to monitor structures including bridges and gas pipelines.   Now researchers at Ecole Polytechnique Fédérale De Lausanne (EPFL) have discovered a new method where optical fibers can identify when they are in contact with a liquid […]

Invisibility Cloaking Could Help to Secure Data Sent Over Optical Fiber

Leave a Comment

Shades of Harry Potter’s invisibility cloak! A recent study in Optica describes a new way to achieve cloaking invisibility. In this method, researchers manipulated the frequency (color) of light waves passing through an object. This approach overcomes critical shortcomings in existing cloaking technologies. The research team says that this technique could help to secure data […]
