Design and characterization of Highly Birefringent ChalcogenideAs_2Se_3 glass Photonic Crystal Fiber with Low confinement Loss

摘要

A new simplified structure of highly birefringent chalcogenide As_2Se_3 glass Photonic Crystal Fiber (PCF) with low confinement loss is designed and analyzed by using fully-vectorial finite element method. The effective indices, confinement losses, birefringence and chromatic dispersion of fundamental polarized mode are calculated in the proposed PCF. It is also shown that As_2Se_3 glass PCF provides lower chromatic dispersion and less confinement loss compared to silica PCF of the same structure and hence such chalcogenide As_2Se_3 glass PCF have high potential to be used in dispersion compensating and birefringence application in optical communication systems.
