Tóm tắt
In this paper, we use As2S3 substrates to design three new solid-core photonic crystal
fiber (PCF) structures with five, six, and seven air-hole rings, respectively, arranged in a square
lattice. We study and analyze the confinement loss characteristics of three structures with the
change of lattice constant (Ʌ), filling factor (d/Ʌ), and the number of air-hole rings to optimize
them at the central wavelength λ = 4.5 µm. The obtained PCFs have almost the same loss
characteristics, however, their values have large differences between the structures. Among them,
small confinement loss is the advantage of the structures in this study. The minimum loss obtained
in the As2S3 substrate square-lattice PCF structure for the seven-ring case is most efficient for
supercontinuum generation (SCG)
