Abstract :
In conclusion, we have developed InGaAs-InAlAs MQW electroabsorption (EA) modulators with integrated waveguides. The modulator chip had a large modulation-bandwidth of 50 GHz and low driving voltage of <3 V. Its prototype module also showed a modulation-bandwidth of >40 GHz. This MQW-EA modulator with integrated waveguides has excellent potential for use in 40-Gbit/s TDM systems
