Abstract

In the context of photonic crystal fibers used in the field of communication. In this paper, a new design of the photonic crystal fibers is designed and proposed. The analysis of the band-gap of gallium lanthanum suphide glass hollow core photonic crystal fiber is conducted using the plane wave expanding method. Furthermore, the properties of confinement loss and velocity dispersion of the waveguide groups of this kind of fiber are investigated using multiple methods. It is discovered that a band gap of 0.15μm in the mid-infrared band is present in this fiber, and the diameter of the cladding air hole has a significant impact on the confinement loss and the waveguide group velocity dispersion. Last but not the least, we got the confinement loss measures 0.0169dB/m at a wavelength of 2.7μm. This PCF is suitable for research in the mid-infrared wavelength range. This design has great application significance in the fields of fiber optics and optical communication of infrared band.
