Optical puff mediated laminar-turbulent polarization transition

Area of Science:

• Nonlinear Optics
• Laser Physics
• Complex Systems

Background:

• Physical systems exhibit probabilistic behavior across scales, blurring quantum and classical physics boundaries.
• Fiber laser systems with mode mixing can display complex dynamics, including transitions to turbulence.

Purpose of the Study:

• To characterize the probability of intermittency during the laminar-turbulence transition in a partially mode-locked fiber laser.
• To introduce and describe a new class of polarization rogue waves at the onset of polarization turbulence.

Main Methods:

• Analysis of intermittency probability in a nonlinear dissipative fiber laser system.
• Investigation of competing processes: proliferation and decay of optical turbulent puffs.
• Identification of polarization rogue waves at the transition point.

Main Results:

• Identified critical behavior for turbulence onset governed by optical turbulent puff dynamics.
• Introduced novel polarization rogue waves associated with the transition to polarization turbulence.
• Demonstrated that probabilistic descriptions offer new insights into laser physics.

Conclusions:

• The study provides a probabilistic framework for understanding laminar-turbulence transitions in fiber lasers.
• Probabilistic characterization of puff-mediated transitions offers a new perspective on complex laser dynamics.
• The findings contribute to a deeper understanding of nonlinear dissipative systems and optical rogue waves.
