Abstract:
Since a cross section of at least a partial segment of a first core has a step-like shape including a quadrilateral shape of a main part and a quadrilateral shape of a protruding part protruding from the main part, respective effective refractive indices of TE polarized waves in the first core and in the second core differ from each other.
