Abstract
Significant enhancement in the direct amplitude modulation bandwidth of an SG-DBR laser has been demonstrated under strong injection-locking conditions, where the wavelength detuning between the master and the free-running SG-DBR slave laser is varied from -8.58 to 13.6 nm. It is demonstrated that the relaxation resonance frequency of a strongly injection-locked SG-DBR laser increases from 1.05 GHz for the free-running case to over 20 GHz.
