Researchers have made a major advance in quantum computing with a new device that is nearly 100 times smaller than the diameter of a human hair. Subscribe to our newsletter for the latest sci-tech ...

A major bottleneck with high-frequency wireless communications is the conversion from radio frequencies to optical signals and vice versa. This is performed by an electro-optic modulator (EOM), which ...

Over the decades, development into silicon photonic modulators – technologically advanced devices that enable the manipulation of light properties – has revealed potential in various network and ...

A nanophotonic diffractive network performs morphological image processing, including dilation and erosion, purely through light propagation.

(Nanowerk News) Liquid-crystal (LC) phase modulators are widely used in optical systems because of their advantages of low power consumption, light weight, flexible bandwidth adjustment, and ...
