Synchronized waltz between light particles in fiber laser cavities
Researchers from the laboratoire ICB (PHOTONICS department) have just demonstrated that light pulses propagating in a laser cavity are capable of communicating with each other over very long distances, and of synchronizing themselves. This work has received editorial preference from the prestigious scientific journal Physical Review Letter.
The effects in question being extremely weak, this study required the development of new analysis tools. This changes the perception that we had of these laser systems where the distant optical pulses were considered until then as evolving independently of each other. To give orders of magnitude, this would amount to demonstrating that two couples dancing the waltz 1km apart would be able to synchronize their footwork, even though no music seems to be playing.
