Abstract
An object is to provide an optical coupling system having a simplified structure and a small size and an optical communication device using the optical coupling system. The object is achieved by an optical coupling system that couples a multi-core fiber and coupled devices to each other using a combination of a polarized light beam control element facing a light incident and emission surface of a multi-core fiber and a polarization-selective diffraction element that is positioned on a side of the polarized light beam control element opposite to the emission surface of the multi-core fiber and that faces the coupled devices.
