In this paper, we experimentally demonstrated the generation of 40GHz phase stable short pulses based on cascaded Mach-Zehnder modulators (MZM). The pulse width is measured to be 4.2ps. The time jitter, extinction ratio (ER) and optical signal-to-noise ratio (OSNR) are measured to be better than 80fs, 18dB and 50dB respectively. The generated optical pulses can be further used for demultiplexing in 4*40GBaud/s optical time-division muletiplexing (OTDM) systems.
Keywords:fiber communication technology; short pulses; Mach-zehnder modulator(MZM); optical time-division multiplexing(OTDM)
