Researchers at ETH Zurich have developed a method for the production of wavy surfaces with nanometer precision. In the future this method could be used, for instance, to make optical components for ...

Diffraction gratings are periodic optical structures that disperse incident light into constituent wavelengths by interference. They form a cornerstone of modern optical instrumentation, underpinning ...

Visual demonstration of the performance of the diffraction grating. The zeroth order transmission refers to light that goes straight through the grating without undergoing diffraction (which should be ...

Diffraction gratings are beautiful things, bending transmitted and reflected light and splitting it into its component wavelengths to create attractive iridescent rainbow patterns. It’s the same ...
