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： An information reproducing apparatus has a medium with a linear tracking mark extending in a scanning direction and a linear data mark extending in a direction orthogonal to the scanning direction. A light control unit irradiates the data mark with a first near-field light polarized in the scanning direction and irradiates the tracking mark with a second near-field light polarized in the direction orthogonal to the scanning direction. A detector detects light scattered by the data mark and the tracking mark irradiated with the first near-field light and the second near-field light, respectively. A signal processing unit processes a first output signal from the detector corresponding to the detected light scattered by the data mark and processes a second output signal from the detector corresponding to the detected light scattered by the tracking mark. The signal processing unit has a control circuit that carries out tracking control in accordance with an intensity of the second output signal and that carries out access control in accordance with an intensity of the first output signal.

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： 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.
