摘要

色散是利用光子方法产生微波信号的潜在限制参数之一。本文从理论上分析了光纤色散参数对双并行双驱动LiNbO3马赫-曾德调制器光子产生的微波/毫米波信号的影响。讨论了具有8倍和16倍微波驱动信号频率的光电探测器的输出强度以及谐波抑制对调制指数(β)和滤波器衰减的影响，发现色散对光域微波信号的产生和传输起主要作用。

Performance analysis of photonically generated microwave signal using a dual-parallel dual-drive Mach-Zehnder modulator in dispersive media

Dispersion is one of the potential limiting parameter for generation of microwave signal using photonic methods. In this paper, we analyse theoretically, the influence of fiber dispersion parameter on the photonically generated microwave/millimeter wave signal using dual-parallel dual-drive LiNbO3 Mach-Zender modulators. Intensity at the output of photodetector having, eight and sixteen times frequency of microwave drive signal and harmonic suppression versus modulation index (β) and filter attenuation is discussed and it has been found that dispersion plays a major role on generation and transmission of microwave signal in optical domain.
