摘要

In this paper,we theoretically investigate the influences of pressure and temperature on the birefringence property of side-hole fibers with different shapes of holes using the finite element analysis method.A physical mechanism of the birefringence of the side-hole fiber is discussed with the presence of different external pressures and temperatures.The strain field distribution and birefringence values of circular-core,rectangular-core,and triangular-core side-hole fibers are presented.Our analysis shows the triangular-core side-hole fiber has low temperature sensitivity which weakens the cross sensitivity of temperature and strain.Additionally,an optimized structure design of the side-hole fiber is presented which can be used for the sensing application.
