The experimental setup shown here incorporates on-chip optical parametric oscillator (OPO) technology to generate a frequency comb of laser-like light covering a wide range of frequencies with very ...

Laser-like light that spans a wide range of frequencies is a powerful tool for science and industry. From semiconductor chip manufacturing to advanced imaging and spectroscopy, broadband coherent ...

A team of physicists at UC Santa Barbara has seen the light, and it comes in many different colors. By aiming high- and low-frequency laser beams at a semiconductor, the researchers caused electrons ...

Researchers were able to control the behavior of various light frequencies that passed through a specially designed cavity. The successful experiment can pave the way fiber optic advances that offer ...

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 ...

The electromagnetic spectrum, or EM spectrum, is the name given to the collection of all electromagnetic radiation in the universe. This is a type of energy that pervades the cosmos in the form of ...

While the light of an ordinary laser only has one single, well-defined wavelength, a so-called ''frequency comb'' consists of different light frequencies, which are precisely arranged at regular ...

Doubling up: Georgia Tech researchers Kyu-Tae Lee (left) and Mohammad Taghinejad demonstrate frequency doubling on a slab of titanium dioxide using a red laser to create nonlinear effects with tiny ...

Researchers develop a highly efficient method to provide coherent light of any wavelength from visible to mid-infrared with a single tiny device. (Nanowerk News) Focused laser-like light that covers a ...
