Researchers from the University of Twente and Harvard University have developed a new way to generate ultraviolet (UV) light on a photonic chip at power levels high enough for real-world use. For the ...

Researchers from the University of Twente and Harvard University have developed a photonic chip that generates milliwatt-level ultraviolet light, about 100 times brighter than previous on-chip UV ...

Ultraviolet-B (UV-B) semiconductor lasers are highly sought for medical, biotechnology, and precision manufacturing applications; however, previous UV-B laser diodes were limited to pulsed operation ...

Humans can only see less than 1% of the electromagnetic spectrum. Here’s why evolution may have intentionally hidden ...

Researchers from Japan have shown that a single organic crystal converts invisible light into visible wavelengths, emitting red light under ultraviolet irradiation and green light under near-infrared ...

A compact ultraviolet-B (UV-B) semiconductor laser diode emitting at 318 nm under continuous-wave operation at room-temperature. The device demonstrates stable UV-B lasing on a low-cost sapphire ...
