... nanometres. Increasingly, biologists have turned to physicists for help in breaking through this “diffraction” limit.
The result has been the development in recent years of several novel techniques ...
... ability to resolve.
"There is a mismatch between nanoelectronics and nanophotonics," says Gan. "Because of the diffraction limit of light, optical circuits are now much larger than their electronic ...
... of electrostatic-based imaging is determined by the number of particle-observations rather than by the diffraction limit of light, our readouts could serve as a form of ultramicroscopy," he said. " ...
Breakthrough could allow optical measurements to beat the 'diffraction limit'
... into tiny spots smaller than the wavelength of the photons in use. These sub-wavelength spots overcome the diffraction limit, thus allowing even the smallest details of an object to be visualized.

... and shorter light wavelengths, which dramatically increases the cost of manufacturing. Also, light has a diffraction limit restricting how small it can be focused. Currently, the minimum feature size ...
... , enabling the scaling down optical devices beyond diffraction limit of the light. Cavities are the confined spaces in lasers where light amplification takes place and this ...
... smaller than the wavelength of the illuminating light source, thus circumventing the normal "diffraction limit," which says that a lens cannot produce an image with a spatial resolution better than ...
... light. Their technique is not limited by the bandwidth constraints of electrical methods or the diffraction limits of light sources.
"We don't need a laser to operate these devices," said Wolfram ...
... the optical transmission, but the 1.4 beamline is very bright and can be focused down to the diffraction limit – an important consideration when the graphene-flake target is so small," Wang says. " ...
... layers on each side.
They have demonstrated that such a semiconductor/dielectric layer, thinner than the diffraction limit, and squeezed between metal layers, can actually emit laser light – a laser ...
... to extraordinary optical properties - hyperlenses make it possible to overcome the so-called "diffraction limit" by imaging features that are significantly smaller than the wavelengths of incident ...
