Abstract :
We demonstrated experimentally the reduction of nonlinearity of an InGaAs/InGaAsP quantum-well electro-absorption (EA) modulator by a dual-parallel modulation scheme at 8 GHz frequency range. Through the experiments, the IMD3, which is the dominant nonlinear product in narrowband, was suppressed by 23 dB and the following 19.6 dB enhancement of SFDR were archived.
