| Abstract: | Ultra-short soliton pulses of 72 fs without any pedestal and CW components are observed from Figure-8 passively mode-locked fiber laser, which is incorporated with a dispersion-imbalanced nonlinear optical loop mirror (DI-NOLM). Bound states of asymmetrical solitons with pulse width of 103 fs and separation of 585.5 fs are also observed. The bound soliton separation and pulsewidth remain unchanged even after passing through 1.2 km single mode fiber (SMF) transmission. |
