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 ...

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 ...

Radio telescopes are instruments that capture faint radio signals from space and convert them into images of celestial bodies ...

Researchers report their insights on the emerging field of complex frequencies excitations, a recently introduced scheme to control light, sound and other wave phenomena beyond conventional limits.

Designers can now measure extremely low levels of light in low-profile applications that require surface-mount packages with the new light-to-frequency converter from Texas Advanced Optoelectronic ...

Did you know you've been cooking your food with light? Most of us have a microwave oven in our kitchens, and that's exactly what they do. When you press start, a device called a magnetron emits a ...

I guess it's like how we use the square root of minus one to solve various equations. It sounda impossible but actually works! Click to expand... Sort've, but I don't think they're going into the ...
