Abstract
In a polarization maintaining multi-core optical fiber according to the present invention, structural birefringence is generated since an elliptic core is applied. In addition, each core is arranged so that a direction of a line connecting between centers of the nearest cores and a long axis direction of a field distribution in each core may be different from each other, and thereby, overlap of field distributions between the nearest cores is reduced. As a result, a crosstalk among cores is reduced.
