Abstract: Provided is an optical filter including a cladding layer, a plurality of metal patterns configured to form a periodic lattice structure on the cladding layer; and an optical waveguide layer on the plurality of metal patterns. Light travels from the optical waveguide layer to the cladding layer. Provided is an optical device using the optical filter.
