Integrated tandem electroabsorption modulators for high-speed OTDM applications

An integrated tandem traveling-wave electroabsorption modulators is demonstrated as an optical short pulse generator and demultiplexer for >100 Gbit/s optical time-division-multiplexed systems. Optical pulses of 4.2 ps width at 30 GHz with an extinction ratio in excess of 30 dB are achieved.
