A time-domain model with high third-order inter-modulation distortion (IMD3) suppression is presented and simulated in the paper. The model can effectively compensate nonlinear distortion effects of microwave photonic links based on dual parallel Mach-Zehnder modulator (DPMZM) with double RF signals. The model results in simple exact expression for harmonic and inter-modulation components at the output...
A scheme to realize a high linear analog photonic link based on a dual-parallel Mach–Zehnder modulator (DPMZM) is proposed and demonstrated in this paper. By using only two electrical phase shifters with $\pi$ phase shift and optimizing the biases of the DPMZM, the third-order intermodulation distortion (IMD3) is completely eliminated by taking all the sidebands in the optical spectrum that produce...
