The figures are as follows:

Fig. 1 Schematic of nonlinear multimode interference (NLMMI) structures: (a) traditional SMF-GIMMF-SMF and (b) our proposed SCF-GIMMF-SMF.
Fig. 2 Simulation results of both MMI structures. Transmission ratio of (a) SMF-GIMMF-SMF structure and (b) SCFGIMMF- SMF structure along the propagation distance at
different pulse peak powers at 1550 nm. Modulation depth of (c) SMF-GIMMF-SMF and (d) SCF-GIMMF-SMF structures when the length of the GIMMF is 20.006 cm.
Fig. 3 Schematic of the experimental setup to measure the modal power distribution in a GIMMF.
Fig. 4 Measured modal power distribution in a GIMMF for both (a) SMF-GIMMF and (b) SCF-GIMMF structure. DGD: differential group delay.
Fig. 5 Measured modulation depth of SCF-GIMMF-SMF structure. Blue dots are experimental data, red line is fitting curve.
Fig. 6 Schematic of the mode-locked fiber laser with a NLMMI structure. LD: laser diode; WDM: wavelength division multiplexing coupler; EDF: erbium-doped fiber; PC: polarization
controller; PI-Isolator: polarization-independent isolator; OSA: optical spectrum analyzer.
Fig. 7 Experimental results of the mode-locked fiber laser using the proposed SA. (a) Optical spectrum, (b) pulse train, (c) autocorrelation trace of the pulse, and (d) the power relationship
between the pump power and output power. CW: continuous wave.
