ABSTRACT:
An optical coupler having a substrate; an optical waveguide provided on the substrate; a multimode fiber optically coupled with the optical waveguide; and a single mode fiber optically coupled with the optical waveguide, the optical waveguide provided on the substrate having a multimode waveguide and a plurality of single mode waveguides, the multimode waveguide being optically coupled with the multimode fiber, the single mode waveguide being optically coupled with the single mode fiber. The above constitution can suppress the creation of branch loss.
