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.
This uptropic of light has diverse applications, especially in defense and optical communications. "The human eye can only see light at certain frequencies (called the visible spectrum), the lowest of which is red light. Infrared light, which we cannot see, has a lower frequency than red light.
The findings, led by Associate Professor Varun Raghunathan, address and overcome the limitations of traditional infrared imaging technologies.
