InGaAs/InGaAsP MQW electroabsorption modulator integrated DFB-LD structure grown by selective area epitaxy

High speed and low chirp light sources are among the most essential components in long distance multigigabit optical communication systems. InGaAsP-InGaAsP electroabsorption (EA) modulator integrated DFB-LDs (EMILD) have attracted special interest because of their small size, low operating voltage and low chirp. In this paper, the optical and electrical characteristics of an InGaAs-InGaAsP MQW EMILD were studied.
