A continuous-wave laser study finds strong third-order nonlinear optical responses in MEH-PPV and PBDB-T polymer solutions, ...

Today, astronomers seek to observe the faintest and most distant objects possible. Extremely Large Telescopes (ELTs), with apertures in the order of several dozen meters, are the next generation ...

Researchers have demonstrated high-efficiency mid-infrared grating waveguide structures fabricated via nanoimprint ...

Researchers at Ulsan National Institute of Science and Technology (UNIST), in Korea, and Fritz-Haber-Institut der Max-Planck-Gesellschaft, in Germany, have recently conducted a study investigating ...

Diffraction gratings separate different wavelengths of light using a periodic pattern embedded in the grating. The diffraction pattern can affect the amplitude and/or phase of the incident light as ...

XRD works by directing X-rays onto a crystalline material and analyzing the angles and intensities of the diffracted beams. The atomic planes within the crystal act as a three-dimensional grating, ...
