All-fiber erbium-doped dissipative soliton laser with multimode interference based on saturable-reserve saturable hybrid optical switch

Abstract

Reverse saturable absorption is essential for the realization of dissipative solitons. In this paper, we introduce reverse saturable absorption by using nonlinear multimode interference (NL-MMI), for the first time, to the best of our knowledge, and obtain a stable dissipative soliton operation. By adjusting the coupling efficiency from multimode fiber to single mode fiber, the absorption properties of NL-MMI can be switched between saturation and reverse saturation. The dissipative soliton in the experiment can be obtained with pulse width of 975 fs, the 3 dB bandwidth with 1555 nm is 16 nm, and the maximum output power is 11.48 mW. The nonlinear absorption optical modulation and high damage threshold characteristics of NL-MMI based ultrafast optical switch provide a new idea for realizing dissipative solitons.

Dynamic Behavior of Optical Soliton Interactions in Optical Communication Systems

“…In appropriate initial conditions, a series of interesting phenomena are generated through those complex interaction processes. [20][21][22][23] Realizing interactions between optical solitons is important for studying interactions between materials and high-intensity light and for learning dynamics of optical solitons. [24][25][26][27] When designing optical soliton devices, in order to ensure stability of optical solitons transmitted, the interactions of another or more optical solitons with the carrier signals should be studied, which can be used as guides for device designs.…”
