From grain-sized to centimeter scale—technique makes mass production of metalenses possible

By Lisa McDonald / December 13, 2019

Metalenses, or flat surfaces that use nanostructures to focus light, are poised to revolutionize cameras, sensors, and displays—if the lenses can be mass produced. Researchers at the Harvard School of Engineering and Applied Sciences found deep-ultraviolet projection lithography can solve this production challenge.

Optical fibers for earthquake monitoring head undersea

By Lisa McDonald / December 3, 2019

It is challenging to effectively monitor seismic quakes deep in the ocean. Lawrence Berkeley National Laboratory researchers and colleagues, who previously used optical fibers to monitor earthquakes on land, tested using optical fibers to monitor earthquakes undersea.

No pressure, no problem—researchers create transparent nanoceramics using pressureless crystallization

By Lisa McDonald / July 16, 2019

Transparent ceramics offer advantages over conventional glass and single-crystal technologies—could transparent nanoceramics be even more advantageous? Researchers show how pressureless glass crystallization could offer an easier way to synthesize transparent nanoceramics.

Optical fibers provide new twist on traditional 3D printing process

By Lisa McDonald / June 7, 2019

Researchers from Notre Dame, Missouri S&T, and the U.S. Air Force Research Laboratory developed a fused filament fabrication method that uses optical fibers as a feedstock. Their method could help create devices ideal for optical applications.

Ferroelectric crystal(lizes) next-gen optical communication idea

By Lisa McDonald / February 15, 2019

A research collaboration achieved ferroelectric domain reversal in single-crystal-architecture-in-glass (SCAG) optical fibers, in spite of the crystals being constrained inside glass. Their research could revolutionize optical data transmission technology.

Optical fibers shake up earthquake monitoring systems

By Lisa McDonald / February 12, 2019

A team of Lawrence Berkeley National Laboratory researchers showed “dark fibers,” unused fiber-optic cables that crisscross the United States underground, could be co-opted to serve as sensors in earthquake monitoring systems.
