World`s most complex 2D laser beam created

Researchers, including one of Indian origin, have demonstrated the most complex 2-D optical phased array ever that can generate high-resolution beam patterns.

`Nanoantennas hold promise for infrared photovoltaics`

In an unexpected discovery that may dramatically improve solar energy panels, scientists have found a new way to generate electricity from infrared light by attaching a metal nanoantenna to the silicon.
