Fourier decomposition algorithm for leaky modes of fibres with arbitrary geometry.
A new algorithm for calculating the confinement loss of leaky modes in arbitrary fibre structures is presented within the scalar wave approximation. The algorithm uses a polar-coordinate Fourier decomposition method with adjustable boundary conditions (ABC-FDM) to model the outward radiating .elds. Leaky modes are calculated for different examples of microstructured fibres with various shaped holes.
