'Groovy' hologram creates strange state of light at visible and invisible wavelengths
Cambridge MA (SPX) Aug 22, 2013
Applied physicists at the Harvard School of Engineering and Applied Sciences (SEAS) have demonstrated that they can change the intensity, phase, and polarization of light rays using a hologram-like design decorated with nanoscale structures. As a proof of principle, the researchers have used it to create an unusual state of light called a radially polarized beam, which-because it can be focused very tightly-is important for applications like high-resolution lithography and for trapping and manipul ... read more
