摘　　要：A method of preparing panda-shaped photonic crystal fibers(PCFs)based on secondary drawing technology is proposed in this paper.The secondary drawing can not only reduce fiber diameter but also reduce core size by adding a glass sleeve.Silver-filled and non-silver-filled panda PCFs are prepared.The two ends of silver-filled panda PCF are connected with a broadband light source and a spectrometer,respectively,and the surface plasmon resonance phenomenon is detected.The secondary drawing technology provides a meaningful reference for the preparation of PCF in the future,and the prepared silver-filled panda PCF can be prepared into an optical fiber filter.
