A Quantum Well Intermixing (QWI) technique has been introduced to modify the transfer function of quantum well electroabsorption (EA) modulator for analog optical links. The linearization of transfer function of EA modulator has been achieved by introducing QW absorption regions differently intermixed each other along the waveguide. A 39.6 dB of IMD2 (2nd order intermodulation distortion) suppression and a 3.6 dB of SFDR (Spurious Free Dynamic Range) enhancement have been achieved.
