摘要： A near-field optical probe has a planar substrate formed with a through-hole and a phase shifter layer translucent to light having a wavelength of illumination light used to illuminate the substrate for producing near-field light. The phase shifter layer is effective to cause a shift of phase in the illumination light by 180 degrees and is provided on the substrate so as to cover one opening of the through-hole to form a microscopic aperture for producing near-field light.

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.

摘要： There is disclosed an optical switch consisting of a support substrate, a movable raw optical fiber, a fixed raw optical fiber, a magnetic member for the movable raw optical fiber, and a leaf spring. The fibers are disposed in a V-shaped groove formed in the substrate. The magnetic member is actuated by an electromagnet disposed above the substrate. The leaf spring pushes the movable raw optical fiber into the V-shaped groove. The structure of the switch is relatively simple. Since the movable raw optical fiber is pushed using the leaf spring, the switch is less affected by the assembly accuracy than conventional. It is easy to make adjustments during assembly. Consequently, high-performance, low-cost, optical switch that can be mass-produced can be offered.

摘要： In an information recording apparatus for recording information onto a recording medium by utilizing a technology in a near-field microscope, the information recording apparatus carries out recording with reliability and density. An optical probe (1) or micro-cantilever (12) utilized in a near-field microscope is used as a recording probe (26). The recording probe (26) at its tip is heated by laser light (28) illumination or heating by an electric heating element to radiate microscopic-region thermal energy through the tip to a recording medium (3). This makes it possible to record microscopically information onto the recording medium (3) that varies in physical properties due to heating. Furthermore, thermal energy is provided to a recording position through an auxiliary heat radiating means thereby enabling recording more positively.

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.
