Subpicosecond soliton pulse generation in the L-band using passive mode-locked figure-eight fiber laser

Summary form only given.Passive mode-locking schemes have been used extensively for generating soliton pulses around 1550 nm in the past couple of years. One of the configurations used is the figure-eight fiber laser (F8-L). These fiber lasers have used standard erbium-doped fiber amplifiers (EDFA). Stable subpicosecond soliton pulses are generated in the L-band wavelength range using passive mode-locked F8-L without any environment control. An L-band EDFA is placed asymmetrically in the nonlinear loop. Soliton pulses with full width at half maximum as short as 200 fs are generated around 1590 nm.
