A flexible pulse shaping photonic structure that
is capable of generating train pulses that hold pulse widths of
approximately 16 ps and a Gaussian profile at a repetition rate
of 20 GHz is proposed and experimentally demonstrated. The key
component is a monolithically integrated reflective semiconductor
optical amplifier (SOA)-electroabsorption modulator device that
operates within the 1.55-μm frequency band. The generated
pulses have low chirp, which is experimentally measured using
a novel linear pulse characterization technique. The pulses have
the potential to be used as seed pulses for optical ultra-wide band
photonic communications systems.
