Stretching the time scales to explore rigid events in nature seemed impossible, yet such feature is now conceivable thanks to a group from the Institute Femto – ST that utilized an innovative estimation technique allowing the capture of such occasions in real time. Such method is presently applied in the field of photonics could aid predict rogue wave events on the surface of the ocean along with other rigid natural procedures.
Such research that was conducted in association with teams from Finland, Canada, and Ireland was introduced in a recent publication. Chaos and instability in physical systems are random natural procedures that are typically highly sensitive to fluctuations in primary conditions, however, tiny they may be. To comprehend such intricate and omnipresent procedure in nature, scientists presently conducted studies involving the movement of light waves and resulting in the formation of ultrafast pulses on a picosecond time-scale.
The study of such procedure in optics provides the benefit of taking place on very small timescales, hence making it feasible to estimate a representative sample of events to reliably characterize its statistical properties. Although they have assisted in enhancing the understanding of such dynamics linked to extreme events, till now such studies have nevertheless been conducted indirectly, due to the responsive time of present detectors that are too slow to gather such rare events.
Current experiments carried out at the Institute Femto – ST in Besancon have made it feasible to combat such limitation. Based on such principle of a time lens, that stretches the time-scale by a factor of 100 while enhancing resolution. Such novel method has allowed scientists to identify giant light pulses in real – time with intensity 1,000 times greater than that of the primary fluctuations from the light source, a laser. For doing so, they utilized a butterfly effect known in optics as modulation instability that magnifies the microscopic trouble intrinsically present in the laser beam moving along telecommunication fibre optics.
The magnitude of such results goes well beyond the niche of photonics, since such sort of background noise is typically considered to be one of the feasible mechanisms behind the destructive waves of rogue that suddenly appear on the surface of oceans and is also considered to be present in other devices like plasma dynamics in the early Universe.
