title: Anisotropic couplers composed of nonidentical cores with nonaligned optical axes.
abstract: The vector modal patterns of anisotropic fiber couplers composed of nonidentical cores with nonaligned optical axes are presented. The four normal modes have different propagation constants with the corresponding electrical-field vectors pointing in different directions.
