Abstract:
We experimental demonstrate stable, simple and pulse width-tunable 40 GHz short time window generation using a dual parallel Mach-Zehnder modulator (DPMZM) driven simply by an electrical clock. The pulse widths are measured to be tunable continuously from 5.6 ps to 12.6 ps by simply adjusting the DC bias voltage of DPMZM. The timing jitter, extinction ratio (ER), optical signal-to-noise ratio (OSNR) and insertion loss (IL) of the generated width-tunable time window are measured to be better than 50 fs, 18 dB, 50 dB and 16 dB respectively.
