Laser-like Beams That Use 250x Less Power
2014-06-06 03:56:27

By Nicole Casal Moore, University of Michigan With precarious particles called polaritons that straddle the worlds of light and matter, University of Michigan researchers have demonstrated a new, practical and potentially more efficient way to make a coherent laser-like beam. They have made what's believed to be the first polariton laser that is fueled by electrical current as opposed to light, and also works at room temperature, rather than way below zero. Those attributes make the...

Light Triggers Ripples In Crystals

University of California - San Diego First propagating surface phonon polaritons in a van der Waals crystal Light can trigger coordinated, wavelike motions of atoms in atom-thin layers of crystal, scientists have shown. The waves, called phonon polaritons, are far shorter than light waves and can be "tuned" to particular frequencies and amplitudes by varying the number of layers of crystal, they report in the early online edition of Science March 7. These properties - observed in...

Sensors, communications devices and imaging equipment that use a prism and a special form of light -- a surface plasmon-polariton -- may incorporate multiple channels or redundant applications if manufacturers use sculptured thin films. "Everyone uses surface plasmon resonance sensors. They are a multi billion-dollar industry worldwide," said Akhlesh Lakhtakia, the Charles Godfrey Binder (Endowed) professor of engineering science and mechanics, Penn State. "This type of sensor provides a...
