As the typical material of two-dimensional transition metal dichalcogenides (TMDs),few-layered MoS2 possesses broadband saturable absorption and a large nonlinear refractive index,which could be regarded as a promising candidate for dual-function photonic device fabrication.In this work,the coexistence of a bound soliton and harmonic mode-locking soliton was demonstrated in an ultrafast fiber laser based on a MoS2-deposited microfiber photonic device.Through a band-pass filter,each multi-soliton state was investigated separately.The bound soliton has periodic spectral modulation of 1.55 nm with a corresponding pulse separation of 5.16 ps.The harmonic mode-locking soliton has the repetition rate of 479 MHz,corresponding to the 65th harmonic of the fundamental repetition rate.The results indicated that there exist morc possibilities of different multi-soliton composites,which would enhance our understanding of multi-soliton dynamics.
