While we’re 100 years past Edison’s fear, uncertainty, and doubt campaign, the fact of the matter is that DC is a bit easier ...

TL;DR: This experiment may not revolutionize telecommunications, but it highlights how accessible these concepts have become outside traditional research labs. Using nothing more than an iPad, a solar ...

Semiconductor laser diodes (SLDs) are often packaged with a photodiode. The output current from this photodiode can be monitored to regulate the output power intensity of the laser diode. SLDs, ...

Communicating underwater has been a challenge for decades. Ever since technologies like radio and lasers came on the scene, people have been looking for a way to operate some sort of similar ...

Miniature AlGaN-based diodes integrate light-emission and light-detection into a single device Applications in solar-blind comms, high-resolution imaging, biosensing, and environmental monitoring ...

A team in France has reported what is claimed to be a novel kind of laser emitting in the orange region of the spectrum, suggesting potential applications in flow cytometry and laser guide stars for ...

Rohm, an electronic components manufacturer based in Kyoto, Japan, has developed a high-output “RLD8BQAB3” laser diode specified for lidar-equipped advanced driver assistance systems (ADAS) to enable ...

Distributed Feedback (DFB) laser diodes are an advanced form of edge-emitting laser, notable for their unique structure, which utilizes a periodic grating instead of a conventional mirror cavity.
