Q: What are diffraction gratings? A diffraction grating is an optical component for spectroscopy that splits light into different wavelengths. A typical diffraction grating has thousands of grooves ...

During the recent decades, nonlinear optical properties of various atomic 1,2,3,4 and other coherent media 5,6 have been well studied due to quantum interference and coherence. As examples and owning ...

This page contains hints, solutions, and advanced challenges for our diffraction grating challenge. If you would like a grating (or a set for your class if you are a teacher), please contact us at ...

Arrays of thousands of tiny "super prisms" controlled by robotic muscles could bring real colour to TV screens for the first time, scientists say. The devices, known as electrically tunable ...
