โœฆ Synopsis

We propose a mode-locked figure-eight fiber laser by utilizing an attenuation-imbalanced nonlinear optical loop mirror (AI-NOLM) for the first time. Stable self-starting passively mode-locked pulses as short as 296 fs are obtained. We have also confirmed that the pulse width of the laser can be varied by changing the amount of attenuation in the AI-NOLM.

We propose and demonstrate a passively mode-locked Erbium-doped fiber laser based on symmetrical nonlinear optical loop mirror. The nonlinear optical loop mirror with intensity-depended transmission can act as an equivalent saturable absorber, which results in passively mode-locking of fiber laser.

## Abstract A novel variable optical attenuator (VOA) based on highโ€birefringence (HiBi) fiberโ€loop mirror is proposed. The HiBi fiberโ€loop mirror is put into the temperatureโ€controlling box. As the temperature increases, the transmission spectrum shifts with nearly unaltered shape. The attenuation
