Researchers invent novel vertical-cavity surface-emitting laser

Researchers at the George Washington University have developed a new design of vertical-cavity surface-emitting laser (VCSEL) that demonstrates record-fast temporal bandwidth. This was possible by combining multiple transverse ...

Prehistoric shark hid its largest teeth

Early sharks that lived 300 to 400 million years ago not only dropped their lower jaws downward but rotated them outward when opening their mouths. This enabled them to make the best of their largest, sharpest and inward-facing ...

Analysis paves way for more sensitive quantum sensors

Quantum sensors can measure extremely small changes in an environment by taking advantage of quantum phenomena like entanglement, where entangled particles can affect each other, even when separated by great distances.

Research produces intense light beams with quantum correlations

The properties of quantum states of light are already leveraged by such highly sophisticated leading-edge technologies as those of the latest sensitivity upgrades to LIGO, the Laser Interferometer Gravitational-Wave Observatory, ...
