Scientists have demonstrated a new fiber-optic sensing method that detects strain and displacement by reading interference patterns directly in the electrical spectrum of a photodetected signal. The ...

Photonics researchers have introduced a novel method to control a light beam with another beam through a unique plasmonic metasurface in a linear medium at ultra-low power. This simple linear ...

Researchers have developed a fast and accurate flexible tactile optical sensor capable of reading Braille. The technology could enable smart readers that convert Braille to speech or text, helping to ...

Using their Mosquito fabrication method, the researchers created a fan-out pattern of multiple thin light paths inside a thin sheet of PDMS. This created four optical channels that could be used for ...

Researchers describe a new high-speed laser writing method for writing data that encompasses two optical dimensions plus three spatial dimensions. The new approach can write at speeds of 1,000,000 ...
