Focused laser-like light that covers a wide range of frequencies is highly desirable for many scientific studies and for many applications, for instance, quality control of manufacturing semiconductor ...

Researchers have built a paper-thin chip that converts infrared light into visible light and directs it precisely, all without mechanical motion. The design overcomes a long-standing efficiency-versus ...

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 ...

The invention of tiny devices capable of precisely controlling the direction and behavior of light is essential to the ...

The speed of light varies in materials, impacting fiber optics, laser systems, and semiconductor lithography through complex electromagnetic interactions.

Researchers propose a method to detect and map low-frequency excitations in nonlinear materials at nanometer resolution, ...

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 ...

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 ...
