Title: Analysis Of Extinction Ratio Of An EAM Integrated With Distributed Reflector Laser Using Wirewidth Modulated Active Regions

Keywords: Distributed Reflector Laser, Electro-Absorption Modulator, Extinction-Ratio, Monolithic Integration, Quantum Confinement Affect, Quantum Wire

In this paper, an electro absorption modulator has been integrated with Distributed Reflector laser using variation of wire width of quantum wire structures. There is a large blue shift observed in quantum wire structure when wire width is reduced. This property has been utilized to design quantum wire EAM integrated with quantum wire Distributed Reflector laser for 1.55┬Ám optical communication. The calculation shows that a 50 nm wire width EAM section with five quantum wire stack is sufficient to provide 20 dB extinction ratio under a reverse bias of 0.12 V.
