| Research Abstract |
We developed optical pulse synthesizers which can generate picosecond pulses with a variety of waveforms including Gaussian and sech2 shapes. The optimal pulse shape for fiber transmission was experimentally clarified by using the optical pulse synthesizer. The optical pulse synthesizer also enables to reshape the pump pulses optimized for generating a uniform SC with wide mode-spacing over 10GHz. We have demonstrated a heterodyne detection in a DWDM transmission system with a multicarrier light source based on optical frequency comb. The error-free 1-Gbps DWDM transmission with 25-GHz spacing has been achieved over 10-km.
