摘要： The present invention has an object, in a near-field optical probe having a microscopic aperture to generate and/or scatter a near field, to obtain a near-field optical probe easy to be made in an array which increases the intensity of a near field to be generated and/or scattered and is adapted for use as an optical memory head.This near-field optical probe is arranged with a planar lens having microscopic lens on a flat surface substrate having an inverted conical or pyramidal hole formed therethrough such that its apex is made as the microscopic aperture, wherein a light source is further arranged thereon to introduce light to the planar lens. Because the arrangement is made such that the planar lens has a focal point positioned at the microscopic aperture, the light given by the light source can be efficiently collected to the microscopic aperture. Also, the above structure can be arrayed and mass produced using a silicon process, thus being adapted for use as an optical memory head.

摘要： A near-field optical probe has a cantilever formed of a transparent material and having a first main surface and a second main surface opposite the first main surface. A base supports the cantilever at the first main surface. A tip extends from the second main surface of the cantilever and has a microscopic aperture at an end thereof. The tip is formed of a transparent material having a higher refractive index than that of the transparent material of the cantilever to increase an amount of near-field light generated or detected by the microscopic aperture. A shade film is formed on the second main surface of the cantilever and on a surface of the tip except for the microscopic aperture.

摘要： There is disclosed a near-field optical head having an microscopic aperture whose size can be varied. The optical head comprises a substrate of silicon. A hole in the form of an inverted cone is formed in the substrate. The top portion of this hole forms the microscopic aperture. A support portion for supporting an actuator is formed on the substrate. The actuator holds a light-blocking film in such a way that the light-blocking film stays in the hole and that the bottom surface of the light-blocking film is flush with the bottom surface of the microscopic aperture. The light-blocking film is moved by the actuator to change the aperture to desired size.

摘要： A near-field optical head has a slider having a minute aperture for emitting near-field light. The minute aperture has a diameter equal to or less than a wavelength of visible light. The slider is supported by a suspension arm for exerting a load, receiving a floating force due to relative movement with a recording medium, and forming a gap between the slider and the recording medium through a balance between the load and the floating force. A light propagating medium has an output end for emitting light. An optical path length shortening structure shortens an optical path length between the output end of the light propagating medium and the minute aperture of the slider. A mirror is disposed over the slider for guiding light emitted from the light propagating medium to the minute aperture of the slider.

摘要： A near-field optical probe has a hole penetrating through a substrate and defining a microscopic aperture at an apex thereof for generating or scattering near field light. The probe is simple and inexpensive to produce and may be manufactured in an array form by forming plural holes in the substrate so that it may be used in an optical memory device. A lens is disposed above the microscopic aperture for focusing incident light and a light source is arranged thereover to introduce light to the lens. A focal point of the lens is positioned at the microscopic aperture, so that the light emitted by the light source can be efficiently collected at the microscopic aperture. The structure can be mass produced using known silicon processing techniques, thus being adapted for use as an optical memory head.

摘要： A near-field optical probe with a resolving power exceeding a diffraction limit of light is provided utilizing near-near-field light. A near-field optical probe is formed by a core and a shading film. The core has a tip surface spotted with inwardly depressed points with respect to the surface. This provides within the tip surface a light intensity distribution in a distributed form instead of a conventional rectangle function. Its Fourier expansion is increased in short-wavelength lattice constant component. Utilizing this component, a near-field optical probe is realized having a resolving power exceeding a diffraction limit of light.
