High-frequency light is useful. The higher the frequency of light, the shorter its wavelength – and the shorter the wavelength, the smaller the objects and details the light can be used to see. So ...

The ability to convert wavelengths of light is a crucial requirement in the improvement of many imaging, sensing and communication technologies. Endoscopy probes are just one example where this ...

Computer chips that cram billions of electronic devices into a few square inches have powered the digital economy and transformed the world. Scientists may be on the cusp of launching a similar ...

Researchers at the Indian Institute of Science (IISc) have fabricated a device to increase or "up-convert" the frequency of short infrared light to the visible range. Up-conversion of light has ...
