Researchers Discover Nanoscale Particles that Ordinary Light Sources can Set Spinning

Science fiction deals with a number of fanciful devices that permit light to interact in a forceful manner with matter, from photon-drive rockets to light sabers. In the past few years, science has indeed begun to catch up; a few results hint at attractive real-world interactions between light and matter at atomic scales, and devices such as vortex beams, tweezers, and optical tractor beams have been developed by researchers.

Novel Nanostructures Developed to Distinguish Between Tiny Differences in Wavelengths of Light

A team of Engineers from Caltech have for the first time created a light detector that integrates two disparate technologies—nanophotonics, which regulates light at the nanoscale, and thermoelectrics, which translates temperature differences straightaway into electron voltage—to differentiate different wavelengths of light, including both infrared and visible wavelengths, at high resolution.

Applying Anderson Localization to Use Visible Light for Sensing Nanoscale Features

The reason why atoms cannot be viewed with the naked eye is that they are very tiny in relation to the wavelength of light — a good example for a common principle in optics, namely that light is insensitive to features that are considerably small relative to the optical wavelength. Yet, a new study published in the journal Science demonstrates that features even 100 times smaller than the optical wavelength can be sensed by light.
