Abstract

Factors influencing the birefringence property of double cladding fiber (DCF) are numerically investigated for DCF with rectangular and D-shape inner cladding. Research shows that the choices of inner cladding shape, outer cladding material and cooling temperature have considerable influence on thermal induced birefringence in the core of DCF. Birefringence increases with the increase of Young's Modulus, thermal expansion coefficient, thickness of outer cladding, and the ellipticity of inner cladding.
