The invention discloses a hybrid surface plasmon polariton (SPP) optical waveguide structure which has the advantages of low transmission loss and strong field limit capability at the same time. The cross section of the waveguide structure comprises a reversed V-shaped (or V-shaped) metal base layer (1), a medium area (2) with high refractive index which is positioned on the metal base layer, anda cladding layer (3). The hybrid SPP optical waveguide structure has the advantages that by means of the medium area with high refractive index which is adjacent to the metal base layer, the light field distribution range of the waveguide structure can be obviously narrowed so as to realize two-dimensional sub-wavelength restriction of a transmission light field, and meanwhile lower transmission loss can be still maintained, therefore, the optical waveguide structure can be used for overcoming the contradiction between the light field limit capability and transmission loss of the existing SPPoptical waveguide so as to provide probability for realizing an optical waveguide chip with an ultrahigh integration level.
