Abstract :
An MQW electroabsorption-modulator integrated DFB laser fabricated by using the in-plane bandgap energy control technique and a low-capacitance semi-insulating BH process is presented. This device has a threshold current as low as 5.4 mA and a modulation efficiency as high as 13 dB/2 V. Modulation at 10 Gbit/s with a modulation voltage of only 1 V peak to peak demonstrates the potential value of this device for electroabsorption modulation at 1.55 mu m.
