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...
Orbital angular momentum Multiplexer/Demultiplexer The multiplexing/demultiplexing module fabricated (a,d) employs a property of light called the "optical vortex" to transmit/receive multiple signals simultaneously through a shared optical medium. The required light waves with different optical vortexes are generated using a combination of a star coupler (b) and an optical-vortex generator (c).

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...

Scientists built a machine that breaks the normal rules of light

Researchers from the National Physical Laboratory (NPL) have investigated how light can be controlled in an optical ring resonator, a tiny device that can...
Rice University researchers studying the effect of light on pinwheels (left) and single C-shaped (right) gold nanoparticles have found an unknown effect on single particles. Stimulating the particles just right produced a near-perfect modulation of the light they scatter via their plasmonic response. The discovery may become useful in the development of chips for next-generation optical components for computers and antennas. Courtesy of the Link Research Group

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...
Researchers shed light on a 150-year old mystery of Light

Researchers shed light on a 150-year old mystery of Light

Light is composed of photons and photons have momentum. But, how light interacts with the matter has remained a mystery for close to 150 years....

Scientists trying to turn light into matter

The hypothesis of the Breit-Wheeler process says it ought to be conceivable to transform light into the issue by crushing two particles of light...
In order to create a molecular chain of rare earths, it is necessary to give the molecule an “asocial character”, as illustrated above

Making molecules antisocial to boost their energy

The light that is noticeable to the human eye is arranged between ultraviolet(high energy) and infrared (low energy). This is the window in which...

This Lensless Camera Technology Doesn’t Have a Lens at All

Scientists at the Caltech have developed a new lensless camera that doesn't require any lenses. They have replaced the curved glass with something that does...
