Recent progress in photonic nanostructures has opened up exciting opportunities for developing compact, highly sensitive, and easily tunable label-free sensors with a spectral response that is easily ...

A wide variety of optical components are used in optical instruments such as laser devices, spectrophotometers, cameras and telescopes. To enhance their performance, these components are often coated ...

In this way, and almost by chance, researchers at TU Wien developed a novel microscopy technique that allows the refractive index of biological samples to be measured at a resolution far below what ...

Researchers at ExCELLS derive a coupled transport model that simultaneously reconstructs refractive-index fluctuations and attenuation coefficients without weak-absorption approximations, and ...
