Ten different electro-optic modulator nonlinearity reduction techniques are presented, and performance parameters of each technique are compared. These parameters include linear dynamic ranges, third-order intermodulation products, relative sensitivities, and operation bandwidths. It is concluded that the feedforward, dual-polarization, and anti-parallel push-pull approaches are more favorable than other techniques in terms of fabrication simplicity, nonlinearity reduction, and sensitivity.
