1. An optical communication apparatus, comprising:
an optical waveguide that is configured to perform propagation only in a reference mode at a first wavelength; and
a light path adjuster that is configured to adjust a light path such that input light is guided to a core of the optical waveguide, wherein the optical communication apparatus is configured to communicate using light of a second wavelength that enables the optical waveguide to perform propagation in at least a first order mode in addition to the reference mode, and
wherein the light path adjuster is configured to adjust the light path due to light being refracted by a lens.
