Light in the nanoworld

A team of international scientists led by Alexander Holleitner and Jonathan Finley, physicists at the Technical University of Munich (TUM), has successfully placed light...

Replacing electricity with light

Researchers are designing a nanoscale photon diode – a necessary component that could bring us closer to faster, more energy-efficient computers and communications that replace electricity with light.

Scientists develop camera to see polarised light

Polarization describes the path along which light’s electric field vector oscillates. An essential quality of electromagnetic radiation, polarization is often omitted in its mathematical...

Scientists discovered new properties of light

Recently, scientists came to know that light can be twisted. This property of light is called angular momentum. Beams with highly structured angular momentum...

Light could drive ions in graphene oixde membranes

Layered graphene oxide membranes (GOM) with densely packed sub-nanometer-wide lamellar channels show exceptional ionic and molecular transport properties. Mass and charge transport in existing...

Unlocking the untapped potential of light in optical communications

In our communication-centered era, Internet traffic has been expanding rapidly. The huge measures of information that travels through the Internet are empowered by immense...

Light triggers gold in unexpected way

Rice scientists surprisingly made a discovery that suggests that exciting the microscopic particles just right produced a near-perfect modulation of the light they scatter. This...
