摘要

摘要: 为了进一步扩充光纤的通信容量，采用了一种利用体全息技术制作波分复用器件的新方法，使其对多波长光能够有效分离，并且对其一些特性进行了研究。在(10×10×10)mm3的双掺杂铌酸锂（掺Fe,Zn）晶体中写入多重体全息光栅，使其对相同方向入射的多波长光进行有效的分离，并且通过理论和实验相结合的方法，对在双掺杂铌酸锂晶体中的波分解复用的一些特性进行研究。实验结果很好地证明了上述方法的可行性，实现了多通道波长解复用，并且得到其一些优点。

Abstract: A new way to make wavelength-division multiplexer using the volume holography technology is proposed to expand the communication capacity of the fiber and separate the light of multi-wavelengths effectively. The properties of wavelength-division demultiplexer were investigated. The holographic gratings were superimposed in 10×10×10 mm3 double-doped LiNbO3 crystals (mixing into Fe and Zn) to separate the multi-wavelengths light transmitting in the same direction. Some theoretical and experimental results on the properties of wavelength-division demultiplexer in double-doped LiNbO3 crystals were given. The experiment result proves that this method is feasible. The multi-channel wavelength-division demultiplexing was realized.
