Abstract

A novel and rigorous analysis of an abrput bend in a dielectric waveguide is presented, obtained by using a combination of the vector finite element method (FEM) formulation and the least squares boundary residual boundary (LSBR) method. The transmission efficiency of an optical wave through a guided-wave structure incorporating a sharp corner is investigated. After validating the newly developed numerical approach for a planar structure, results for a more realistic structure with a three-dimensional structure are also presented.
