The present invention discloses a field local enhancement device based on hybid plasmonic waveguides. The device comprises three layers of structures consisting of a first layer of structure, a secondlayer of structure and a third layer of structure which form a coaxial conical structure from inside to outside layer by layer, the three layers of structures are respectively medium with a high refractive index, medium with low refractive index and precious metal, when a radially polarized beam vertically enters the structures from the bottom end of a circular cone, the structures can effectively reduce the loss to allow more luminous energy to perform propagation towards the top end, the luminous energy is gathered at the top end and the peak of the circular cone has a high electric field enhancement effect so as to achieve higher focusing performances. The structures can be applied to an ultra-high density integration circuit to have very important application for achieving nanometer photon device design and integration, novel light source, communication fiber processing and micro-nano sensing detection.
