## Abstract A delay‐time tunable, actively mode‐locked erbium‐doped fiber ring laser is demonstrated by using a voltage‐controlled phase‐locked phase shifter as an inherent timing module. By changing the voltage from −3.35 to 3.6 V, the maximum tuning range of the phase and the delay time of the op
## Abstract Multiple mode instabilities in erbium‐doped fiber laser are undesirable due to the large amplitude noise in the laser. One scheme is proposed to suppress this kind of instabilities by inserting a highly nonlinear photonic crystal fiber in the ring cavity. The results show that the nonli
