Power-Guided Asymmetrical Vector Dissipative Soliton Molecules in a Compact Fiber Resonator

Vector dissipative soliton molecules (VDSMs) can be promising for polarization multiplexing transmission applications. We report a nonlinear polarization rotation (NPR) vector dissipative soliton molecule laser. The laser realizes three-type vector dissipative soliton molecules of directly generated “1+2” type, “2+2 type, and outer-cavity projected super-position “2+‘2+2’” type just by changing the pump power. It's proved that the different generated methods of vector soliton molecules in Hamiltonian systems can also be realized in dissipative systems. This is also the first time that multiple different generated methods of vector dissipative soliton molecules are realized in a fiber resonator based on NPR. The results proved the VDSMs' structures can be controlled, which can be potentially applied in optical frequency comb, optical communication systems, optical logic processing, optical detection, etc.
