| 中文摘要: |
| 回顾了基于超结构光纤光栅的光学编/解码器的发展，介绍了基于超结构光纤光栅的编/解码器的工作原理，以及详细讲解了近期研发的两种编/解码器.采用±π/2相移的编/解码器能够隐秘地将光学码信息隐藏于编码波形中，有效地改善编码安全性.单输入多输出的编/解码器能够实现同时产生一组光学码，并且将这些光学码分配至不同的光路. |

| In this paper,an overview of the development of the superstructured fiber Bragg grating (SSFBG) based en/decoder is given.The operation principle of the SSFBG based en/decoder is introduced.Two recently proposed SSFBG based en/decoder are presented.The ±π/2-SSFBG based en/decoder has the ability to conceal the code information in the encoded waveform well and improve the security.The single-input multiple-output en/decoder is capable of generating a group of optical codes and distributing the codes into different optical paths. |
