TAPERED PHOTONIC CRYSTAL FIBER, ITS MANUFACTURING METHOD, AND METHOD FOR SPLICING PHOTONIC CRYSTAL FIBERS

摘要

PROBLEM TO BE SOLVED: To provide a tapered photonic crystal fiber capable of easily and excellently splicing photonic crystal fibers different in core diameter.;SOLUTION: One end of the photonic crystal fiber 2 having a core 10 extending along a fiber center axis and a clad 9 having a plurality of fine holes 9a extending along the core 10 and arranged around the core is covered with a protection pipe 3. The protection pipe 3 is heated to fuse and integrate the photonic crystal fiber 2, and the part coated with the protection pipe 3 is tapered.;COPYRIGHT: (C)2005,JPO&NCIPI
