Polaritons offer the best of two very different worlds. These hybrid particles combine light and molecules of organic material, making them ideal energy transfer vessels…
Researchers have used liquid crystals to create magic windows that produce a hidden image when light shines on them. Credit: Felix Hufnagel, University of Ottawa…
Technology could make it possible to use radio emissions from cell phone networks to wirelessly power sensors and LEDs. Researchers have developed a new metasurface-based…
Researchers at MIT have shown how one could improve the efficiency of scintillators by at least tenfold by changing the material’s surface. This image shows…
A newly created nano-architected material exhibits a property that previously was just theoretically possible: it can refract light backward, regardless of the angle at which…
Humans experience the world in three dimensions, but a collaboration in Japan has developed a way to create synthetic dimensions to better understand the fundamental…
A 2 mm by 2 mm integrated photonic chip developed by Jaime Cardenas, assistant professor of optics, and PhD student Meiting Song (lead author) will…
Researchers have combined computational ghost imaging and x-ray fluorescence measurement in a high-resolution and efficient way to produce chemical element maps. The new method could…
MIT physicists have detected a hybrid particle in an unusual, two-dimensional magnetic material. The hybrid particle is a mashup of an electron and a phonon.…
Artist’s concept. The new observations record a key crossover from classical to quantum behavior. The world we experience is governed by classical physics. How we…

The innovation could be a game-changer for communication technologies, such as phones and internet connections. A team from UCF has developed the world’s first optical…
A metasurface made of arsenic trisulfide nanowires (yellow) transmit an incoming near-infrared frequency (red) as well as its third harmonic ultraviolet frequency (violet), which would…
Detecting light beyond the visible red range of our eyes is hard to do, because infrared light carries so little energy compared to ambient heat…
