Latest Advances in Photonics Focuses on Light–Matter Interactions in Time-Varying Media

At the interface between two media, light is partly reflected backwards into the medium where it came from and partly transmitted into the neighboring medium, like a light ray entering a sparkling pool of water.

Developmental Milestones of Photonic Matrix Multiplication and Related Applications

There has been an ever-growing demand for artificial intelligence and fifth-generation communications globally, resulting in very large computing power and memory requirements. The slowing down or even failure of Moore's law makes it increasingly difficult to improve their performance and energy efficiency by relying on advanced semiconductor technology. Optical devices can have a super-large bandwidth and low power consumption.

Scientists Open New Path Toward Producing Room-Temperature Superconductivity with Light

Much like people can learn more about themselves by stepping outside of their comfort zones, researchers can learn more about a system by giving it a jolt that makes it a little unstable – scientists call this "out of equilibrium" – and watching what happens as it settles back down into a more stable state.
