By using high-quality mirrors, scientists can create optical traps—known as optical cavities—that control vacuum fluctuations and, in turn, modify the magnetic or electric properties of a ...

Optical cavities are highly sensitive to changes in their environment, making them ideal for sensing applications. Cavity-enhanced sensing techniques, such as cavity ring-down spectroscopy (CRDS) and ...

So a given 39-cm cavity might support modes with 1234567, 1234568 and 1234569 wavelengths, and as the cavity warms and expands the 1234567 wavelength mode will wink out at the lower end of the ...

Researchers have developed a new microscope that can visualize the optical response of surfaces at an unprecedented spatial ...

Optical gyroscopes work on a physical principle called the Sagnac effect. Under laboratory conditions, optical gyroscopes are among the most sensitive devices available to measure rotation. The ...
