A Caltech team has developed a highly efficient method to provide coherent light of any wavelength from visible to mid-infrared with a single tiny device ...

At the core of the breakthrough is an optical parametric oscillator (OPO), a resonator that converts incoming laser light into new frequencies using a nonlinear crystal. For decades, OPOs have been ...

Spectroscopy, the study of light-matter interactions, is vital for understanding molecular properties and advancing ...

Did you know that the world around us is filled with different types of light waves ? From the warm glow of the sun to audible radio waves and invisible gamma rays, electromagnetic waves (action ...

The Sun emits electromagnetic radiation across a broad spectrum, including visible, infrared, microwave, radio, ultraviolet, X-ray, and gamma-ray wavelengths. Visible light, comprising wavelengths ...

A research team has successfully developed a self-locked Raman-electro-optic (REO) microcomb on a single lithium niobate chip. By synergistically harnessing the electro-optic (EO), Kerr, and Raman ...

Under Chairman Ajit Pai, the Federal Communications Commission’s (FCC) work on light-touch regulation and spectrum allocation has made a big difference in helping advance next-generation technologies.
