The human eye can only see light at certain frequencies (called the visible spectrum), the lowest of which constitutes red light. Infrared light, which we can't see, has an even lower frequency than ...

Use left and right arrow keys to seek audio. In a new study published in Science, researchers have developed a new method for detecting infrared light by changing its frequency to a corresponding ...

High-quality optical ring resonators can confine light in a small volume and store it for millions of roundtrips. They have enabled the dramatic size reduction from laboratory scale to chip level of ...

Researchers have for the first time demonstrated that a specific class of oxide membranes can confine, or 'squeeze,' infrared light -- a finding that holds promise for next generation infrared imaging ...

Non-ionizing radiation includes the spectrum of ultraviolet (UV), visible light, infrared (IR), microwave (MW), radio frequency (RF) and extremely low frequency (ELF). Lasers commonly operate in the ...

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 ...
