Selected Spectrum Transmission Of Nolm Under Ds And Dsr Mode-Locking States

Taking all the pulse instantaneous power into consideration, we investigate the pulse interference dynamics of dissipative soliton (DS) and dissipative soliton resonance (DSR) through a discrete model based on nonlinear optical loop mirror (NOLM). We numerically and experimentally acquire that the reflection and transmission spectra of the NOLM under DS and DSR regimes show significant wavelength selectivity which results from the intensity-dependent nonlinearity. The wavelength selectivity phenomenon may be helpful for in-depth understanding on different operation dynamics of saturable absorber in passive mode-locked lasers.
