| 摘 要： | 提出了一种基于超结构取样光纤光栅的光码多分址(OCDMA)编解码器.以修正Walsh码为例,研究了利用间隔光0.8 nm的超结构取样光纤光栅编解码器的实现方法,通过控制温度实现了基于超结构取样光纤光栅的OCDMA编解码器的变址.研究表明:采用该编解码器实现谱域编码,可以避免光纤光栅串联方案中多个光纤光栅接点引起的损耗,易通过应力或温度变化调节中心波长、尺寸小及调谐方便,有利于实用化.

| Abstract: | A novel en-/de-coder scheme based on super-structure optical fiber gratings is proposed for optical code division multiple access(OCDMA)system.It can realize code in wavelength domain and avoid the shortcoming of the loss generated by conventional multiple fiber gratings in series.And the en-/de-coder scheme can easily adjust the center wavelength by changing strain or temperature.It is very small and very tunable.These features lead to commercialization.The en-/de-coder scheme based on super-structure optical fiber gratings with 0.8 nm interval is researched.It is shown that changing address is achieved by center wavelength drift of super-structure optical fiber gratings by changing the temperature. |
