Summary: | Photonic crystal fibers (PCFs) have been studied extensively in recent years. An
important use of PCF is polarization maintaining. The previous polarization
maintaining fibers, also known as highly birefringent fibers are mainly based on
Photonic Band Gap (PBG) Guiding PCFs and Index-Guiding PCFs. Recently, a new
class of PCF – Hybrid PCF, which guiding light by both PBG Guiding and
Index-Guiding mechanisms, was introduced. Due to its intrinsically asymmetric
structure, it has great potential for designing a highly birefringent fiber. This project
aims to design a highly birefringent Hybrid PCF for polarization maintaining use.
The influences on photonic band gap properties and the effects on birefringence of
structural variations in Hybrid PCF are investigated. Different methods are
incorporated together to design a highly birefringent fiber based on Hybrid PCF
structure. Finally, a birefringence of 3.34 10-2 of at wavelength of 1.55μm is
achieved. |
