Abstract :
We investigate the small signal frequency response for a low chirp Quantum Dash directly modulated laser in combination with an off-the-shelf passive optical filter. We report the enhancement of channel-bandwidth and the eye reshaping using such a transmitter assembly that allows transmitting 10 Gbit/s signal from 0 km up to 100 km using constant bias conditions.
