Abstract

In this paper several approaches to expand the field profile of a laser beam are studied. The power coupling efficiency and fiber coupling loss are discussed in detail. To achieve this, the rigorous vector finite element method is used to calculate the modal propagation properties and the least squares boundary residual method is employed to calculate the coupling loss, the reflection coefficient and the alignment tolerances of these devices.
