PHOTONIC BAND GAP OPTICAL FIBER CAPABLE OF PREVENTING THE GENERATION OF ADDITIONAL COSTS BY REMOVING ELEMENTS WHICH GENERATES OPTICAL LOSS, AND A MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A photonic band gap optical fiber and a manufacturing method thereof are provided to effectively manufacture a band gap optical fiber within a short time by using a photonic crystal structure.;CONSTITUTION: A core part(1) is extended in one direction. At least one first tube(2) surrounds the core part. The cross section of the core part in a direction which is vertical to the one direction is located in the coplanar formed with a first axis and a second axis. The length of the first axis direction is less than the length of the second axis direction. The first axis and the second axis are vertical to each other. The cross section of the core part has the elliptic shape. The core part comprises vacuum or the air. Each of at least one first tube comprises quartz or silicon oxide.;COPYRIGHT KIPO 2010
