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.

Researchers Leverage 3D Design Space to Create a Metamaterial with Robust Optical Properties

Metamaterials, made up of small, repeated structures, engineered to produce desired interactions with light or sound waves, can improve optical devices used in telecommunications, imaging and more. But the functionality of the devices can be limited by the corresponding design space, according to Lei Kang, assistant research professor of electrical engineering at Penn State.

New Method to Amplify Optical Signals Without Increasing Unwanted Noise Content

Weak optical signals are common in many science and technology applications. However, they are difficult to detect or process due to the incoherent noise that is inherently present in any system.

Researchers Find the Optimal Way to Generate High-Energy Protons Using Laser-Plasma Interaction

Proton therapy is a precise and effective treatment for tumours in sensitive areas of the body, such as the brain or the eyes, with the advantage that it spares healthy tissue. In this procedure, protons (positively charged particles) are strongly accelerated and directed with precision into the tumour tissue, which is destroyed in the process. However, this efficient method of treatment has so far required large accelerators, which is why it is only available in major treatment centres.
