Abstract:A theoretical analysis of the mechanism of wavelength compatibility in an electroabsorption (EA) modulator integrated distributed feedback (DFB) lasers was made based on identical-epitaxial-layer (IEL) integration scheme. It was shown that, as a result of carrier-induced bandgap shrinkage and temperature rise in the active region, the gain profile of quantum well material will shift towards the longer wavelength side of the excitonic absorption peak, making it possible to achieve wavelength compatibility in an IEL structure. Based on these results, IEL integrated sources were designed and fabricated. These devices have shown excellent static characteristics as well as desirable high-speed modulation performances, with a small signal modulation bandwidth of about 8 GHz.
Keywords:identical epitaxial layer (IEL) structure  DFB laser  EA modulator  high-speed integrated source
