    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: An optical head for optical recording/reading apparatus, which records and reads information with high reliability, by making use of an optical interaction with a medium in a minute area, on a high density medium revolving at high speed. It has a structure, in which an optical waveguide mechanism applies a loading force to a slider 6 receiving a buoyant force, and a system for introducing a light to the slider 6 and a system for applying the loading force are integrated into an identical body. As the result, a stable posture regulation of the slider 6 and an increase of the light intensity of irradiation on the medium can be achieved, and it becomes possible to record and read information with high reliability. Furthermore, by disposing a minute structure in the vicinity of an edge in the surface facing the medium of the slider 6, so that the minute structure can come closer to the medium, further improvement in high density can be made.

    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.

    摘要: An optical microcantilever for a scanning near field microscope has an optical waveguide for propagating light. The optical waveguide has a longitudinal axis, a light input/output end, a free end opposite to the light input/output end, and a tip formed at the free end of the cantilever and having a microscopic aperture at an end thereof. A support section has a first portion supporting the optical waveguide, a second portion and a third portion. The second portion has an optical element guide channel formed in the support section for supporting an optical element acting on light entering the optical waveguide or on light exiting from the optical waveguide and for determining a position of the optical element. The third portion is disposed between the first portion and the second portion and has a surface disposed at an angle of inclination relative to the longitudinal axis of the optical waveguide. The light input/output end of the optical waveguide projects above the third portion for reducing a coupling loss between the optical element and the optical waveguide.
