The formation of dissipative solitons is influenced by various factors, such as spectral filtering effect and Kerr nonlinearity effect. This interaction leads to the possibility of mode locking on a large range of parameters, generating pulses with completely different types and evolution from conventional physical laws and optical properties, tolerating higher nonlinear effects, and effectively avoiding the generation of pulse splitting. The laws of physics and optical properties have made significant improvements compared to traditional light pulses.

The researchers led by Professor Zhang Haikun from Jinan University designed the use of two materials with different optical properties, BP and SnSe 2, which were stacked together through van der Waals forces to form heterojunctions. This allowed the materials to maintain their respective optical properties while achieving electron migration and interband hopping through interlayer coupling, thereby achieving optical synergy and further optimizing the optoelectronic properties of the composite materials.

The work titled "Picosecond Dissipative Soliton Generation in Ytterbium Doped Fiber Lasers Based on BP/SnSe2-PVA Mixture Saturable Absorber" was published in Frontiers of Opto Electronics.

This composite material is made into a saturable absorber to prepare fiber lasers, demonstrating the enormous potential of composite materials composed of two two-dimensional materials in ultrafast optical applications.
