Study of Coupling Length of Concentrically Curved Waveguides
In this paper, we propose a method based on Helmholtz equation to determine the coupling length of the light propagating in concentrically curved waveguides by the conformal transformation. After the transformation, the concentrically curved waveguides are regarded as straight directional couplers,...
