a, Optical performance and response time of different electronically controlled optical devices, where different colors indicate different material types. b, Optical performance and stimulus ...

Scientists have achieved a breakthrough in light manipulation by using topological insulators to generate both even and odd terahertz frequencies through high-order harmonic generation (HHG). By ...

Researchers know this well: controlling the light inside a microchip has always been an arduous challenge. The imperfections of the material create reflections and rebounds that affect the direction ...

Forward-looking: Scientists have discovered a new method for controlling special light waves in two-dimensional materials, a breakthrough that could lead to the development of faster communication ...

Nonlinear optics has long relied on high-power lasers, whose spatial and temporal coherence ensures efficient nonlinear frequency conversion. However, a new study challenges the traditional assumption ...

Scientists at the University of East Anglia have uncovered a hidden property of light that allows it to twist, spin and behave differently—without mirrors, materials or special lenses. In a ...
