Abstract
We demonstrate the use of cross-absorption modulation in an electroabsorption
modulator to actively mode-lock a semiconductor fiber laser at 10 GHz. The
laser cavity also comprises a linearly chirped fiber Bragg grating to obtain
wavelength tunable operation based on the dispersion tuning approach. The
laser exhibits uniform output pulse characteristics throughout the tuning
range. We also investigate the impact of using different types of optical
pump signals on the output pulses. Finally, we demonstrate the application
of the mode-locked laser for all-optical
clock recovery.
