Abstract:
A polarization converter of the invention includes a core part that wave-guides an electromagnetic wave and a cladding part that is provided around the core part. The core part includes a conversion part converting a polarization state of the electromagnetic wave. A cross-sectional shape of the conversion part in a plane orthogonal to a propagation direction of the electromagnetic wave is a shape formed by cutting off a portion of a rectangular or square shape along a jagged diagonal line.
