基于相位调制的线性化微波光子链路
Linearized microwave photonic link based on phase modulation
摘要
Abstract
In the previous structures, the third-order intermodulation, second-order intermodulation and the second harmonic distortions cannot be suppressed simultaneously. To overcome the above problems, a lin-earized microwave photonic link based on phase modulation is designed. The proposed link can suppressed the third-order intermodulation, second-order intermodulation and the second harmonic distortions simultane-ously by using single-sideband modulation and balanced-photodetection. In addition, the power of the funda-mental signal can be doubled, and the chromatic dispersion is also eliminated. The theoretical analysis is per-formed, and the simulated analysis is also carried out by employing Optisystem. The simulated results show that the SFDR of the proposed MPL is increased by 17dB, comparing with the conventional SSB-phase-modu-lation MPL.关键词
