Using the ski jump, the authors built beam scanners on chips called photonic integrated circuits (PICs). The cantilevers can be fabricated using processes that have been established for conventional ...

A surprising trick that allows a beam of light to be completely absorbed even in the thinnest of layers: Using mirrors and lenses, a 'light trap' can be constructed, in which the light beam is steered ...

The direction of that beam can be adjusted simply by changing the polarization of the incoming light. In laboratory tests, the researchers converted infrared light with a wavelength of about 1530 ...

Whether in photosynthesis or in a photovoltaic system: if you want to use light efficiently, you have to absorb it as completely as possible. However, this is difficult if the absorption is to take ...
