Characterization of Erbium Doped Photonic Crystal Fiber
Abstract: Photonic crystal
fibers (PCFs) are a new emerging research area, and have been undergoing rapid
development in recent years due to their unique and excellent optical
properties and features.Studies on the characteristics of various types of PCFs
have been reported. However, characterization onerbium-doped PCF has not
previously been investigated. Therefore, in this paper, we have modeled an erbium-doped
core PCF which has 7 rings of hexagonal air holes. The PCF structure, with a
perfectly matched layer (PML), is modeled and simulated using Finite Element
Method (FEM) via COMSOLsoftware. The PML is optimized by varying the radius and
thickness of the layer. Modal properties of thePCF have been investigated in
terms of its effective index of the supported fundamental mode,confinement loss
and thickness of the perfectly matched layer. This erbium-doped PCF has a
confinement loss of 1.0E-6 at 1500 nm and a maximum effective refractive index
of 1.476. This paper gathers usefuldata, which could be used for studying the
characteristics of a PCF.
