Broadband supercontinuum generation in highly nonlinear fiber with carbon-nanotube-based passively mode-locked erbium-doped fiber laser

We present a broadband supercontinuum (SC) generation in highly nonlinear fiber (HNLF) with carbon-nanotube (CNT)-based passively mode-locked erbium-doped fiber laser (EDFL). The passively mode-locked EDFL incorporating CNT-based saturable absorber (SA) has achieved a pulse width of 570 fs with a repetition rate of 18.3 MHz.
