Photonic crystal fiber is superior to conventional fiber due to its unique light conducting characteristics and flexible structure.High birefringence makes it suitable for polarization-preserving fiber,fiber optic gyro and other fiber devices.Based on the analysis of the basic principles of birefringence characteristics through the understanding and summary of reading research related literature,this paper introduces the research progress at home and abroad with the main goal of improving the birefringence characteristics of photonic crystal fibers in recent years,high birefringence can be obtained by increasing the asymmetry or changing the stress in different directions.The stress can effectively obtain high birefringence characteristics.With the continuous development of artificial metamaterials,photonic crystal fiber has a very wide range of applications and profound practical prospects in optical communication and other fields.
