Abstract :
In the present paper we report the realization of a mode-locked hybrid distributed Bragg reflector (HDBR) laser for picosecond optical pulse generation at 10-GHz repetition rate, 12.7-ps 2-mW optical pulses, with 400-MHz locking bandwidth have been obtained by using a saturated (95% of peak reflectivity) Gaussian Bragg grating. Linear phase gratings have shown even better results in terms of stability and output power (7 mW), whereas so far 15 ps of pulsewidth has been achieved, mainly limited by the spectral bandwidth of the grating. Key features of this realization are the intrinsic simplicity and the compactness of the laser source.
