Abstract :
We report on the use of a delay interferometer (DI) to transmit 10-Gb/s optical signals from a 1.5-GHz-bandwidth reflective semiconductor optical amplifier (RSOA). The DI acts as a two-tap optical equalizer, compensating for the severe bandwidth limitation imposed by the RSOA. We demonstrate the successful transmission of 10.7-Gb/s nonreturn-to-zero signals over 50-km standard single-mode fiber with a 0.3-dB penalty.
