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 ...
From left to right: Schematic of the nonlinear optical mirror used for up-conversion imaging. Energy diagram showing the sum frequency generation process used for up-conversion. Representative ...
Researchers have created a nanoscale structure that traps infrared light in a layer just 40 nanometers thick—over 1,000 times ...
