A 20 GHz optical pulse train was generated by a sinusoidally-driven InGaAs/InAlAs multiquantum well intensity modulator operating at low voltages (from –2 to –3 V DC bias with a 3.2 V peak-to-peak RF signal). An approximately transform-limited optical pulse train width of 8ps and a spectral width of 40 GHz were obtained.
