Abstract :
The 10 Gbit/s high power output InGaAsP multiple-quantum well electroabsorption modulator, which can be tunable in the full C-band, is demonstrated. The semiconductor optical amplifier is integrated to compensate for optical losses. Operation over the full C-band, which ranges from 1530 to 1565 nm, is obtained using temperature and bias tuning. Under these operating conditions, modulated fibre output power as high as +4 dBm, dynamic extinction ratio exceeding 8.5 dB, and dispersion penalty of less than 2 dB for 1600 ps/nm of fibre, are achieved across the entire band.
