Controlling light with a material three atoms thick

Most of us control light all the time without even thinking about it, usually in mundane ways: we don a pair of sunglasses and put on sunscreen, and close—or open—our window blinds.

Metasurfaces control polarized light at will

For years, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have engineered metasurfaces to manipulate light based on its polarization state. That research has contributed to advances ...

New high-speed method for spectroscopic measurements

Researchers at Tampere University and their collaborators have shown how spectroscopic measurements can be made much faster. By correlating polarization to the color of a pulsed laser, the team can track changes in the spectrum ...

Competitor fears Musk's SpaceX could 'monopolise' space

The launching of thousands of satellites into low Earth orbit by tech billionaire Elon Musk's SpaceX threatens the "de-facto monopolisation" of space, the head of competitor Arianespace Stephane Israel has warned.
