A linearization method for a multiple quantum well (MQW) electroabsorption analog modulator is studied. We analyze the nonlinear characteristics of the light-voltage (L-V) transfer curve in a MQW electroabsorption modulator and estimate its intermodulation distortion (IMD). We propose a novel linearization method, the integration of twin MQW modulators with optical 3 dB couplers. This method can reduce IMD_2 and IMD_3 simultaneously by only adjusting the modulation depth and the bias voltage of each modulator. Results of simulations show that the method can suppress IMD_2 and IMD_3 to below -65 dBc at a modulation depth of 10% without any serious loss of optical signal power or increase in chirp.
