| 摘 要： | 对于全光纤调制，以前的研究者多着眼于单通道调制的研究。为了利用光纤的巨大承载能力，对多通道调制进行研究也是非常必要的。从理论上研究了多通道全光纤声光调制器。利用微扰形式的光纤耦合模方程，讨论了一根光纤多个部分受到周期性微扰的情况，并进一步讨论了多通道全光纤调制的情况，最后讨论了相位匹配条件下的输出结果。这对于实验、器件研究具有指导意义。

| Abstract: | The researchers generally studied one channel all fiber modulator. In order to develop the great capability of optical fiber, the multiple channel all fiber acousto optical modulator should be concerned. The multiple channel all fiber acousto optical modulator is studied theoretically. The perturbed coupled mode theory is used to discuss the solutions of coupled mode equations for optical fiber when there are multiple parts being perturbed, and the multiple channel modulation is analyzed. The results can be used as a basis of experimental research. |
