Abstract: In this paper, we have proposed a novel structure of the fabrication of a chalcogenide As2Se3 glass photonic crystal fiber (PCF) with increased core diameter. As comparision with the normal PCFs in which silica glass is used as core material, the proposed PCF has following feature; firstly we have used the chalcogenide As2Se3 glass as core material in which the first ring area contains no air holes. Then the proposed PCF has a large core area chalcogenide As2Se3 glass photonic crystal fiber. There are low chromatic dispersion in the proposed PCF comparied to normal As2Se3 glass PCF. The chromatic dispersion is almost flat in the range of 2.4 micrometer to 4.0 micrometer range when the air hole diameter ‘d’ is 1.0 micrometer and air hole space ‘˄’ is 2.0 micrometer.
Keywords: Chalcogenide As2Se3 glass, chromatic dispersion, photonic crystal fiber.
