Nanotechnology experts at Sandia create first terahertz-speed polarization optical switch

September 14, 2017 – 5:00 am

ALBUQUERQUE, N.M. — A Sandia National Laboratories-led team has for the first time used optics rather than electronics to switch a nanometer-thick thin film device from completely dark to completely transparent, or light, at a speed of trillionths of a second. The team led by principal investigator Igal Brener published a Nature Photonics paper this […]

Plasmonic crystal alters to match light-frequency source

October 30, 2013 – 2:05 pm

A device like a photonic crystal, but smaller and tunable ALBUQUERQUE, N.M. — Gems are known for the beauty of the light that passes through them. But it is the fixed atomic arrangements of these crystals that determine which light frequencies are permitted passage. Now a Sandia-led team has created a plasmonic, or plasma-containing, crystal […]
