Researchers from Trinity College Dublin's School of Engineering have built a powerful new machine that lets us watch precisely what happens when tiny particles—far smaller than a grain of sand—hit a surface at extremely high ...
A University of Colorado Denver engineer is on the cusp of giving scientists a new tool that can help them turn sci-fi into reality.
Multi-wavelength light sources are required for optical transceivers to increase data. However, scaling the laser array size increases thermal crosstalk, which may affect laser efficiency and reliability.
Lasers that are fabricated directly onto silicon photonic chips offer several advantages over external laser sources, such as greater scalability. Furthermore, photonic chips with these "monolithically" integrated lasers ...
Macquarie University researchers have demonstrated a technique to dramatically narrow the linewidth of a laser beam by a factor of over ten thousand—a discovery that could revolutionize quantum computing, atomic clocks and ...
In a first for the field, researchers from The Grainger College of Engineering at the University of Illinois Urbana-Champaign have reported a photopumped lasing from a buried dielectric photonic-crystal surface-emitting laser ...
Researchers have discovered a simple yet powerful way to protect atoms from losing information—a key challenge in developing reliable quantum technologies.
An international research team led by the Helmholtz-Zentrum Hereon has, for the first time, succeeded in visualizing and quantifying the complex airflow dynamics directly above the ocean surface in high resolution. Using ...
