Abstract: PURPOSE: An optical waveguide and a bidirectional optical transceiver are provided to separate bi-direction signal inside the core of an optical waveguide by using a wavelength selective filter. CONSTITUTION: An optical waveguide(110) comprises a core(111), a cladding(112), and a wavelength selective filter(113). The core transmits light. The cladding protects the core. The cladding maintains light inside the core with the total reflection effect. The wavelength selective filter is formed inside the core and separates the bidirectional signal. The wavelength selective filter changes a transmission light(200) of a cladding mode(210) transmitted through the cladding into a core mode(220) or the cladding mode. The light transformed through the wavelength selective filter passes through the wave length selective filter.
