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.

Natural three-dimensional nonlinear photonic crystal

Nonlinear photonic crystals (NPCs) are transparent materials that have a spatially uniform linear susceptibility, yet a periodically modulated quadratic nonlinear susceptibility. These engineered materials are used extensively ...
