| 摘 要： | 通过研究了光栅的低阶色散和高阶色散、脉冲宽度对该系统的影响,详细推导了应用光纤光栅的光纤微波毫米波传输链路系统在时域中的理论表达式,实验证实了,由光栅低阶色散引起的相移会导致射频信号一系列频率的消失,而高阶色散和脉冲宽度引起的信号失真都是与时间相关的。结果还表明:高阶色散会引起恢复射频信号的幅度随时间线性衰减,而脉冲宽度导致信号幅度呈二次抛物线递增。

| Abstract: | The influences of low-order dispersion and high-order dispersion of gratings as well as pulse width on the system were studied.The theoretical expression of fiber grating microwave/millimeter-wave over transmission system in time domain was derived.The experimental results show that the phase shift caused by low-order dispersion of fiber gratings leads to the disappearance of the frequency of RF signal.Nevertheless,the signal distortion induced by high-order dispersion of gratings and pulse width is time-dependent.High-order dispersion results in the amplitude of the recovered RF signals decreasing linearly with time,and the pulse width brings its increasing following quadratic curve. |
