Monolithic Integration of Electro-Absorption Modulators and DFB Lasers by Modified Double Stack Active Layer Approach

Monolithic electro-absorption modulated distributed-feedback(DFB) lasers are proposed and fabricated by using a modified double stack active layer.The 38mA threshold,9dB extinction ratio (from 0.5V to 3.0V),and about 5mW output power at the 100mA operation current are achieved.Compared with other reported results (only 1.5mW at the same operation current) of the traditional stack active structure,the proposed structure improves the output power of devices.
