14 February 2005Study on the birefringence of the circular-core side hole fiber
The finite element method was used to analyze the interior stress distributions and the birefringence of the side hole fiber. The paper has analyzed the dependence of the birefringence of the side hole fiber on the side holes' physical dimensions. The calculation result shows that the fast axis of the fiber is along the line which links the two holes' centers, the geometrical birefringence can be neglected, and the birefringence can be improved through increasing the radius of the side holes or reducing the distance between the core and the side hole centers.
