Abstract
Fundamental properties such as mode field distribution, real effective refractive index, imaginary effective refractive index, confinement loss of two new kinds of honeycomb photonic crystal fibers are successfully studied by using Full-Vectorial Finite element method (FV-FEM). Low confinement loss 0.1×10-4dB/km is achieved at wavelength 1.55µm in hollow core honey comb PCF by removing 6-air holes in cladding region with air hole diameter 1.38µm in cladding region, pitch 2.3µm and air core diameter 0.2µm.
Highlights
Photonic Crystal fibers (PCFs) have diverse applications in supercontinuum generation, nonlinear optics, telecommunications, sensors, soliton, lasers, medical instrumentations etc [1-5]
Fundamental properties such as mode field distribution, real effective refractive index, imaginary effective refractive index, confinement loss of two new kinds of honeycomb photonic crystal fibers are successfully studied by using Full-Vectorial Finite element method (FV-Finite Element Method (FEM))
If we introduce a small air core as defect in core region of honeycomb PCF we call it as hollow core or air-guiding PCF
Summary
Photonic Crystal fibers (PCFs) have diverse applications in supercontinuum generation, nonlinear optics, telecommunications, sensors, soliton, lasers, medical instrumentations etc [1-5]. Potential advantage of a hollow core is that one can dynamically introduce materials into the core, such as a gas that is to be analyzed for the presence of some substance They can have a much higher effective-index contrast between core and cladding and can have much stronger confinement for applications in nonlinear optical devices, polarization-maintaining fibers. In this fiber, light guiding mechanism is due to completely photonic band gap effect[7]. The Full Vectorial Finite element method (FEM) is generally advantageous in complex geometries of photonic crystal fiber It is a full vector implementation for both propagation and leaky modes and cavity modes for two dimensional Cartesian cross sections in cylindrical co-ordinates.
