Abstract
With the progress of study on fiber optic gyroscope (FOG), the higher demand for performance of polarization maintaining fiber (PMF), and miniaturization is one of the important development direction. Compared to other stress-induced PMF, the birefringence of elliptical cladding type PMF has small effect when we make stress area smaller, and it can meet the requirements of fiber optic gyroscope. Therefore, 40 microns ultrafine diameter elliptical cladding type polarization maintaining fiber can be the preferred option of the FOG towards light, small, spiritual direction. In this paper, we use finite element method to analysis stress-induced birefringence of 40 microns ultrafine diameter elliptical cladding type PMF, get the stress contours on cross-section of PMF, and calculate the stress birefringence, the polarization mode field distribution and modal birefringence. Under the given simulation conditions, the magnitude of stress birefringence in core is about 10-4, and the magnitude of model birefringence is about 10-4. The results show that 40 microns ultrafine diameter elliptical cladding type PMF has a uniform stress field distribution and a large birefringence. It is conductive to achieve miniaturization of PMF.
