    摘要： An optical microcantilever for a scanning near field microscope comprises a support section, a cantilever-shaped optical waveguide, and a light blocking wall. The optical waveguide has a free end, a fixed end fixed to the support section and terminating in a light input/output end, and a tip formed at a side of the free end of the cantilever and having a microscopic aperture at an end thereof. The light blocking wall blocks the transmission of light scattered from a region of the light input/output end in the direction of the tip of the optical waveguide.

    摘要： An optical microcantilever has an optical waveguide for propagating light. The optical waveguide has a first side, a second side opposite to the first side, and a tip portion formed on the first side and at a free end of the optical waveguide. The tip portion has a microscopic aperture. A light blocking film is disposed on the first side of the optical waveguide. A reflecting film is disposed on the second side of the optical waveguide. A reflecting member forms part of the reflecting film and is disposed at the free end of the optical waveguide. The reflecting member has a generally planar surface for reflecting light propagated by the optical waveguide and for guiding the reflected light towards the microscopic aperture to generate near-field light at the microscopic aperture.

    摘要： A near-field optical head has a planar substrate having a first surface, a second surface disposed opposite to the first surface, and an inverted conical or pyramidal hole extending through the first and second surfaces. The inverted conical or pyramidal hole has at least one fine aperture formed at an apex thereof and disposed in the first surface and having at least one curved slant surface. An optical waveguide extends into the inverted conical or pyramidal hole of the planar substrate for propagating light along an optical path. A mirror is disposed in the optical waveguide for bending in the direction of the fine aperture the optical path of the light propagated through the optical waveguide.
