Light confinement in a 3-D space

The emerging services such as data center cloud interconnection services, ultra-bandwidth video services, and 5G mobile services stimulate the fast development of photonic integrated circuits (PIC), which can meet the increasing ...

Strain engineering of 2-D semiconductor and graphene

Strain engineering usually refers to a kind of material processing technology which aims to regulate the properties of materials or optimize related devices' performance by inherent or external strain. In recent years, with ...

Improving quantum dot interactions, one layer at a time

Osaka City University scientists and colleagues in Japan have found a way to control an interaction between quantum dots that could greatly improve charge transport, leading to more efficient solar cells. Their findings were ...

Bending light to engineer improved optical devices and circuits

Rainbows are formed when light bends—or refracts—as it enters and exits a water droplet. The amount that the light bends depends on the color of the light, resulting in white light being separated into a beautiful spectrum ...

Intelligent nanomaterials for photonics

Since the Nobel Prize in Physics was awarded for research on graphene in 2010, 2-D materials—nanosheets with atomic thickness—have been a hot topic in science. This significant interest is due to their outstanding properties, ...

White graphene exhibits high defect tolerance and elasticity

Because of their unique physical, chemical, electrical and optical properties, two-dimensional (2-D) materials have attracted tremendous attention in the past decades. After revealing the realistic strength and stretchability ...

Quantum light squeezes the noise out of microscopy signals

Researchers at the Department of Energy's Oak Ridge National Laboratory used quantum optics to advance state-of-the-art microscopy and illuminate a path to detecting material properties with greater sensitivity than is possible ...
