Abstract: A method and an apparatus for fabricating a multi-element compound nanostructure are provided. The method includes steps of providing a substrate in a chamber, providing a particle-beam having plural first particles, providing a particle source having plural second particles to fill the chamber therewith and focusing the particle-beam on the substrate and depositing the first particles with the second particles on the substrate to form the multi-element compound nanostructure. In comparison with the conventional ones, the provided method is more simplified and has a great potentiality for being applied.

Abstract: The present invention provides a light-enhancing component and a fabrication method thereof by using the focused-ion-beam. In the present invention, the surface plasmon polariton structure is coated on the surface of the optical fiber so as to form the light-enhancing component. When the light passes through the optical fiber, the luminous flux transmitted through the aperture on the surface plasmon polariton is enhanced, and the light beam smaller than the diffraction limitation can be transmitted to the far-field, i.e. the nano-optic sword is formed. The light-enhancing component of the present invention can be used for the optical data storage, the optical microscopy, the biomedical detections and the lithography to perform the extra optical resolutions beyond the diffraction limitation.
