Optical tweezers use light to immobilize microscopic particles as small as a single atom in 3D space. The principle behind the tweezers is the momentum transfer between light and the object held. Light pushes onto objects that make the…

According to photonics researchers, the amount of time taken up by an optical signal limits the amount of data that can be carried. Temporally shorter signals allow more data to be squeezed into a given time duration, in a method called…
