摘要:
The present invention has an object to obtain an optical waveguide probe which is formed in a hook form to illuminate and detect light by a manufacture using a silicon process. This optical waveguide probe is formed in a hook form and structured by an optical waveguide 1 sharpened at a probe needle portion 5 and formed of dielectric and a substrate 2 supporting this optical waveguide 1. This optical waveguide 1 is formed overlying the substrate 2. The optical waveguide 1 is structured by a core 8 to transmit light and a cladding 9 smaller in refractive index than the core 8.

摘要:
The invention concerns a recording apparatus for reproducing information recorded on a recording medium by utilising near-field light. The recording apparatus comprises: an aperture element having two microscopic apertures to scatter near-field light; a light illuminating means for introducing illumination light to the recording medium such that near-field light is created on a surface of the recording medium; a first light detecting means for detecting first propagation light caused by one of the microscopic apertures scattering the near-field light and for converting the detected first propagation light into a reproduced signal the reproduced signal representative of recorded information; a second light detecting means for detecting second propagation light caused by the other of the microscopic apertures scattering the near-field light, and for converting the detected second propagation light into a control signal, the control signal for use in controlling the spacing between the aperture element and the recording medium; and a control means for controlling a spacing between the aperture element and the recording medium based on the control signal.

A tip of a probe is sharpened and a level difference portion 6 in a boundary zone between a base portion 5 and an elastic functioning portion 4 is formed into a tapered configuration. The diameter of the elastic functioning portion 4 is made smaller than that of the base portion 5. Also, a part of the elastic functioning portion 4 is shaped into a constricted configuration. Also, the probe material is an optical fiber and this probe is composed of a core portion 2 that propagates light therethrough and clad portions 3 that differ in refractive index from each other. And the portion of the probe that excludes a aperture is clothed by a metal film cladding 7.
