Description

Breather: Profile and energy of soliton are oscillating periodically.
Mechanisms of breather:
Modulation instability 
Hopf bifurcation 
Subharmonic entrainment 
Polarization instabilities leading to desynchronization of the orthogonal states of polarization 
This work theoretically and experimentally demonstrates the effect of the slow scale (thousands of round trip times) polarization instabilities on the emergence of breather like spatiotemporal structures by using a nonlinear polarization rotation (NPR) mode locked fibre laser.
