Infrared light, which we can’t see, has quite a low frequency. 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 diverse applications, especially in defence and optical communications, IISc noted in a press release.
