In recent years, van der Waals crystals have evolved from scientific curiosities into a versatile platform for exploring novel quantum phases and unconventional nanophotonic phenomena. Their layered ...

Researchers have experimentally realized an optical effect predicted over 75 years ago: the Tellegen effect, where electric ...

Light does not “think” in any human sense. Still, under the right conditions, it can behave in a way that looks uncannily like a memory system.

A new Stanford-designed optical amplifier uses energy recycling in a resonator to deliver strong, low-noise amplification with far less power.

As digital data streams increase in speed and data rate, losses in PCB traces become ever more of a bottleneck.

Researchers have built the smallest OLED pixel ever made—just 300 nanometers across—without sacrificing brightness. By redesigning the pixel with a nano-sized optical antenna and a protective ...

Optical transceivers are packaged devices that convert electrical signals into light pulses for transmission over fibre optic cables.

An international team of researchers has shown that superconductivity can be modified by coupling a superconductor to a dark electromagnetic cavity. The research opens the door to the control of a ...
