We demonstrate that the use of an optimized bi-electrode reflective semiconductor optical amplifier as remote modulator reduces the chirp. Our simulation shows that the chirp reduction is due to the carrier density profile in multi-electrode reflective semiconductor optical amplifiers. As a result of the chirp reduction, penalties for transmission are reduced from 6 to 4.5 dB on standard fiber at 2.5 Gb/s over 50 km. Using tri-electrode devices, a penalty of 3 dB is obtained for the same transmission conditions.
