| 摘 要： | 研制了一种新型的两通道声表面波(SAW)全光纤声光调制器,建立了多通道声波与光纤中光导波相互作用的耦合模方程并求出其解。SAW全光纤声光器件由两通道SAW器件和单模光纤构成。光纤嵌入SAW器件,光纤中的光导波被声表面波调制,由于两个通道中的SAW具有不同的中心频率,所以光纤中的光导波可以被具有不同频率的两个通道的SAW同时调制。测试了器件,实现了全光纤相干调制解调。

| Abstract: | A novel two-channel all-fiber acousto-optic modulator is fabricated.The coupled mode equations based on the interaction of multi-channel surface acoustic waves(SAW)and the guided optical wave(GOW)in fiber are put forward and their solutions are derived.The all-fiber acousto-optic modulator is composed of two-channel SAW device and single mode fiber.Single mode fiber is imbedded into the surface acoustic wave device and the GOW in fiber is modulated by surface acoustic waves which have different center frequ... |
