Photonic downconversion link with linearization and full spectrum utilization
2017
We propose and verify a scheme to both improve the gain and linearity of the downconverted analog photonic link. We utilize the different electro-optic coefficients of the phase modulator to realize the suppression of the third-order intermodulation distortion. And the link gain is improved by full spectrum utilization. The simulation results show that the SFDR is improved by ∼14dB. And the link gain is increased by ∼13.43dB compared to the linearized downconversion link without full spectrum utilization.
