Abstract

We demonstrate a three-core optical fiber with qusi-rectangular core. Due to fiber-core´s geometry asymmetry the high birefringence properties are predicted and estimated. Based on the finite element method, the birefringence characteristics are analyzed numerically at 1550nm wavelength. The mode birefringence is calculated to be B_m>10^-5. The origin of birefringence is attributed to the core´s shape and the inner retained stress. By simulating inner self-stress distribution we discuss the contribution to mode birefringence.
