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

Obtain, evaluate, and communicate information about the properties and applications of waves. SP4.b Develop and use models to describe and calculate characteristics related to the interference and ...

Diffraction is a classic optical phenomenon accounting for light propagation. The efficient calculation of diffraction is of significant value towards the real-time prediction of light fields. The ...

A combined team of engineers from Jiangsu University and Harvard University used a non-destructive, light diffraction fingerprint technique to detect viral infections in cells. Their paper is ...

Researchers at Harvard University and Jiangsu University developed a technique for not only identifying infected cells, but also tracking the infection over time as the cells developed. They published ...

Beauty is in the eye of the beholder, and when it comes to “sunbursts” in photos – those points of light with rays streaking out of them – people often have polarizing views. Optical diffraction is ...

Light scattering as the basis for size determination of many objects has been explored for a long time. It was Gustav Mie, author of the Mie Scattering Theory, who studied gold nanoparticles in ...

A U.K.-Portuguese research group is proposing a new solar cell design based on diffraction gratings – optical components that split and diffract light into several beams. They claim this could lead to ...

Scientists from the Quantum Technologies Group at the Institute of Physics Zagreb, in collaboration with a colleague from the ...

Every lens has a sweet spot, the aperture where the image sharpness is at its best. If the aperture becomes larger, lens errors will become visible. When the aperture is closed, lens diffraction will ...
