In contrast to conventional mode-locked lasers with a single output, multiplexed soliton lasers exhibit a significantly broader range of potential applications. In this chapter, we summarize several commonly used multiplexed dissipative soliton fiber lasers, including wavelength multiplexing, bidirectional multiplexing, and multistate multiplexing. Multiwavelength mode locking can be utilized as multichannel light sources and microwave generation. Bidirectional and multistate multiplexing would be effective methods for the generation of dual-frequency combs. Finally, some novel methods to realize the multiplexed dissipative soliton fiber lasers are discussed.
