“…The phenomenon is due that the nonlinear effect in the cavity becomes stronger and the activities between solitons are intensified frequently, resulting in more coupling and collision opportunities between pulses, which will make the GVLVS change from a stable pulse complex to PRVS. Different from the ordinary two groups of PRVS effects , 27,28 phase delay of each component exactly corresponding to π/2 . It is calculated according to temporal evolution of oscilloscope.…”

Coupling between modes is crucial for generating coherent structures and spatiotemporal chaos in optical systems. In an ultrafast fiber laser with birefringence, the stable pulse is viewed as a vector soliton (VS) with two orthogonal modes nonlinearly coupled through the Kerr effect and gain/loss. However, the dynamics of a VS in the presence of linear coupling is unperceived despite linear coupling playing a significant role in various optical systems. Here, it is shown that a local linear coupling between polarization modes in lasers facilitates brand‐new nonlinear states, including stationary, breathing, and chaotic VSs. The observed solitary states can be regarded as emergent phenomena when two particles (polarization modes) in a system have a simple interaction (linear coupling), which are ubiquitous in biology, chemistry, and complex systems. It is found that linear coupling is essential for sustaining the internal balance between two modes within the VS. Chaotic dynamics of VS emerge under weak linear coupling, while the two modes lose trapping due to the birefringence in the absence of linear coupling. This work can offer new insight into the two‐mode nonlinear system and inspire research interests in the intelligent manipulation of ultrashort pulse lasers.

“…Another important parameter for the generation of solitons is the fiber birefringence. Depending on the fiber birefringence and polarization-asymmetry in the laser cavity, different types of solitons can be generated, including scalar solitons 8 , group-velocity-locked vector solitons 9 – 12 , polarization-rotation vector solitons 13 and polarization-locked vector solitons 14 . Both group-velocity-locked vector conventional solitons (GVLVCS) 9 , 10 and group-velocity-locked vector dissipative solitons (GVLVDS) 11 , 12 have been reported in fiber lasers.…”

Laser cavities which can generate different types of ultrashort pulses are attractive for practical applications and the study of pulse dynamics. Here, we report the first experimental observation of both conventional solitons (CS) and dissipative solitons (DS) generated from a single all-fiber laser with net-anomalous dispersion. A birefringence-related intracavity Lyot filter with an adjustable extinction ratio enables the switching between the two types of ultrashort pulses. Depending on the polarization controller settings and the pump power, either chirp-free CS with a pulse energy of 406 pJ and a spectral bandwidth of 5.1 nm or up-chirped DS with a pulse energy of 5.1 nJ and an optical bandwidth of 9.6 nm can be generated. Similar polarization features are observed when the laser switches between different soliton operations as both CS and DS are group-velocity-locked vector solitons. Our work paves a novel way to generate dissipative solitons with a relatively high pulse energy (one order of magnitude larger than for CS) and a large chirp directly from an all-fiber net-anomalous-dispersion cavity through birefringent filter management.
