local bandgap energy of an InGaAs/InGaAsP MQW structure was precisely adjusted by in-plane Eg control in one-step selective area MOCVD growth. The technique was then applied to an MQW electroabsorption modulator integrated DFB laser. Experimental results showed superior device characteristics, such as a high extinction ratio of 25 dB and low threshold current of 15 mA.
