摘要：

An accurate full vectorial treatment of the leaky modes in Bragg fibres with high refractive index variations is presented. The model can describe arbitrary functions of the relative permittivity inside the fibre. Boundary conditions are substituted by smooth continuous functions. This allows the use of very precise numerical and analytical approaches to the solutions. As a concrete example, a calculation of leaky modes inside a Bragg fibre with a quadratic periodic variation of its relative permittivity profile is made.
