Menlo's optical frequency combs are a core component of optical clocks, such as this one at JILA. (Courtesy: GE Marti/JILA) This year marks the 20th anniversary of the first time an optical-frequency ...

Cornell researchers have built a programmable optical chip that can change the color of light by merging photons, without ...

Silica optical fiber is well recognized as a decent nonlinear optical medium to carry out nonlinear optics due to the long-interaction length and high-power density in the fiber core. However, the ...

Scientists have found a way to make atoms dance with light, quite literally. In certain crystals, vibrations called phonons ...
