Primary performance data for passive fiber-optic devices is provided by spectral measurement of optical insertion loss (IL) and polarization-dependent loss (PDL). Often used to characterize optical ...

Artificial intelligence (AI) is known for its high energy consumption, especially in data-intensive tasks like health monitoring. To address this, researchers have developed a flexible paper-based ...

At St. Paul's Cathedral in London, a section of the dome called the Whispering Gallery makes a whisper audible from the other side of the dome as a result of the way sound waves travel around the ...

A team of researchers at the Ming Hsieh Department of Electrical and Computer Engineering has created a new breakthrough in photonics: the design of the first optical device that follows the emerging ...

A nanoscale optical device has been developed that allows independent control over the intensity and phase of light. By applying voltage, this innovative device can freely manipulate the phase and ...

Optical communication has revolutionized long-distance data transfer, but scaling it down to microchips is tougher. Now, though, a new technique means optical components can be integrated into general ...

Silicon photonics is an emerging and rapidly-expanding design platform that promises to enable higher-bandwidth communication and other applications. One of the best qualities of silicon photonics is ...
