Abstract :
A photonic integrated transmitter for RZ transmission provides 50 ps optical pulses on-off modulated at a bit rate of 3 Gbit/s. BER performance is measured in a back-to-back transmission experiment and compared to NRZ transmission using the same photonic circuit with the laser operated CW. A 2.8 dB improvement in receiver sensitivity is obtained for the RZ case.
