All-optical wavelength multicasting at 4times10 Gb/s with extinction ratio enhancement has been demonstrated based on pump-modulated four-wave mixing in a nonlinear photonic crystal fiber. We show ...

Acoustic wave coupling in dual-wavelength orthogonal polarized Brillouin random fiber laser (BRFL) based on polarization-maintaining (PM) fiber is characterized experimentally for the first time. Dual ...

Watching that wave made me fall in love with big wave surfing. I paddled it for the first time recently, I had an injured foot but paddled out and got the most amazing vision out there. It’s an insane ...

Astronomers have used mysterious fast radio bursts, or millisecond-long bright flashes of radio waves from space, to help ...

In a nutshell The Mystery Solved: A 9-day global seismic signal was caused by a massive “standing wave” trapped in a Greenland fjord after a climate-triggered landslide. First Direct Evidence ...
