"Optical modulators are devices that help generate high-speed signals from optical fibers. They can convert or change things like the intensity, phase, or frequency of the light using electrical ...

Spatial control of the phase and amplitude of ... and holography to interferometry and optical tweezers, reports Neil Savage. Digital spatial light modulators (SLMs) provide fine-grained control ...

Scientists have made a surprising discovery: they have managed to manipulate light particles in such a way that they can ...
