This invention relates to a method for manufacturing selective area grown stacked-layer electro-absorption modulated laser structure, comprising: step 1: forming a selective growth pattern of a modulator section on a substrate; step 2: simultaneously growing a 2-stacked-layer active region structure of a modulator MQW layer and a laser MQW layer by the first epitaxy step; step 3: etching gratings, and removing the laser MQW layer in the modulator section by selective etching; and step 4: completing the growth of the entire electro-absorption modulated laser structure by a second epitaxy step.
