Abstract:

This report describes the development of a mode-locked erbium-doped fiber laser. Active mode-locking was achieved by modulation of a multiple quantum well MAW device by Stark shifting the absorption of the quantum wells. The MQW device could also act as a saturable absorber, so that the laser could be passively mode-locked. Pulses as short as 11 pico seconds were produced. The cavity was injection mode-locked at both the fundamental and second harmonic period of the cavity round-trip time.
