Researchers have shown, for the first time, that transmission of ultrastable optical signals from optical clocks across tens of kilometers of deployed multicore fiber is compatible with simultaneous ...

Modern-day communications rely on both fibre-optic cables and wireless radiofrequency (RF) microwave communications. Reaching higher data transmission capabilities is going to require technologies ...

In the era of big data, signal processing faces significant challenges in terms of capacity and energy consumption due to the torrent of data to process. With over 90% of data transmitted through ...

Let’s think of the last time you sent data without wires. We’re not talking WiFi here, but plain optical signals. Free-space optical communication, or FSO, is an interesting and easy way to transmit ...

Once a month or so, I have the privilege of sitting down with Editor-in-Chief Elliot Williams to record the Hackaday Podcast. It’s a lot of fun spending a couple of hours geeking out together, and we ...

Researchers have shown how ultrastable optical signals from optical clocks can be transmitted across tens of kilometers of deployed multicore fiber carrying telecommunications data. Nazanin Hoghooghi, ...

Scientists have developed a compact optical amplifier based on a photonic chip that vastly outperforms traditional optical amplifiers in both bandwidth and efficiency. This breakthrough could reshape ...

What's behind the IEEE 802.3cz Multi-Gigabit Glass Optical Fiber Automotive Ethernet standard. Optical vs. electrical links in automotive Ethernet. Details behind various compliance and conformance ...

Researchers have developed a new way to recognize human emotions by combining fiber-based physiological signals with thermal images of the face. The portable emotional recognition system could ...

A focus-stacked macro photograph of a fabricated gallium phosphide photonic chip featuring multiple spiral waveguides and other test structures. The chip width is just 0.55 cm across. Due to the high ...
