Your library or personal account may give you access

Abstract

A downconverting analog photonic link based on DP-QPSK MZM is proposed. The nonlinear distortions components are significantly suppressed using DSP-based post-compensation method. Finally, an SFDR of 123.3 dB-Hz2/3 is achieved, which is improved by 21.5dB.
