用计算全息制作啁啾光纤光栅的研究

A Study on ComputerGenerated Holograms for Recording Chirped Fiber Grating Corrugations

提出了一种制作啁啾光纤光栅的新方法———计算全息法,对该方法进行了理论分析,描述了制作过程和实验装置,给出了一个用计算全息制作的啁啾参数为F=32π,长度为21.6μm的样品,得到了该样品在光学系统中的再现像。

A new method of the fabricating chirped fiber grating by using the computergenerated hologram (CGH) is proposed and analyzed theoretically. The experimental setup and fabrication process are described. We present an example of such CGH by which a section of chirped fiber grating was produced with chirped parameter F=32π and grating length L=21.6 μm finally we give a reconstructed image of the CGH.
