Abstract:
An optical microcantilever for a scanning near field microscope, the optical microcantilever comprising:an optical waveguide having a light input/output end, a free end for propagating light incident from the light input/output end, a first side, and a second side opposite to the first side; a tip formed on the first side and at the free end of the optical waveguide and having a microscopic aperture; a light-blocking film disposed on the first side of the optical waveguide; a reflecting film disposed on the second side of the optical waveguide; and a reflecting member forming part of the reflecting film and disposed at the free end of the optical waveguide, the reflecting member having a generally planar surface for reflecting light propagated from the light input/output end of the optical waveguide and for guiding the reflected light towards the microscopic aperture of the tip, or for reflecting light propagated from the microscopic aperture towards the light input/output end of the optical waveguide.
