  • near field optical data storage using a solid immersion lens
    Applied Physics Letters, 1994
    Co-Authors: B. D. Terris, H. Jonathon Mamin, D Rugar, W.r. Studenmund, Gordon S. Kino
    Abstract:

    A near‐field optical technique, using a new type of solid immersion lens (SIL), has been developed and applied to the writing and reading of domains in magneto‐optic material. The SIL is a truncated glass sphere which serves to increase the numerical aperture of the optical system by n2, where n is the index of refraction of the lens material. Using a SIL made from n=1.83 glass and illuminating with 780 nm light, we have achieved a 317 nm Spot Size. We have resolved a 500 nm period grating, and written and read 350 nm diameter magnetic domains. The technique should be capable of a 125 nm Focused Spot Size using blue light.A near‐field optical technique, using a new type of solid immersion lens (SIL), has been developed and applied to the writing and reading of domains in magneto‐optic material.

  • characterization of a fresnel zone plate using higher order diffraction
    Journal of Synchrotron Radiation, 2002
    Co-Authors: Akihisa Takeuchi, Yoshio Suzuki, Hidekazu Takano
    Abstract:

    The performance of a Fresnel zone plate has been tested by observing the focusing property of higher-order diffraction. The Fresnel zone plate was fabricated by the electron-beam lithography technique. The zone material was made from 1 µm-thick tantalum and the outermost zone width was 0.25 µm. The third-order Focused Spot Size measured by the knife-edge scan method was 0.1 µm full width at half-maximum at an X-ray energy of 8 keV, which is exactly equal to one-third of the first-order focal Spot Size.

  • diffraction limited microbeam with fresnel zone plate optics in hard x ray regions
    X-Ray Micro- and Nano-Focusing: Applications and Techniques II, 2001
    Co-Authors: Yoshio Suzuki, Akihisa Takeuchi, Hidekazu Takano, Takuji Ohigashi, Hisataka Takenaka
    Abstract:

    X-ray microbeam using Fresnel zone plate as a beam focusing device has been tested at an undulator beamline of Spring-8. The zone material is tantalum with thickness of 1 micrometers , and the zone structure is fabricated by using electron beam lithography technique. The outermost zone width of the zone plate is 0.25micrometers . By utilizing a fully coherent illumination, a Focused Spot Size near to the diffraction- limit (0.3micrometers ) has been achieved at an X-ray energy of 8 keV. The measured beam profiles shows good agreement with the theoretical profile. The measured diffraction efficiency agrees well with theoretical value within an X- ray energy region from 6 keV to 10 keV. A scanning microscopy experiment has also been performed in order to evaluate the spatial resolution. Fine structures of up to 0.2micrometers are clearly observed in the measured image. The modulation transfer function derived from the measured image is 10% at 0.2micrometers line and 0.2micrometers space.© (2001) COPYRIGHT SPIE--The International Society for Optical Engineering.

  • diffraction limited microbeam with fresnel zone plate optics in hard x ray regions
    Japanese Journal of Applied Physics, 2001
    Co-Authors: Yoshio Suzuki, Akihisa Takeuchi, Hidekazu Takano, Takuji Ohigashi, Hisataka Takenaka
    Abstract:

    A hard X-ray microbeam with zone plate optics has been tested, and preliminary experiments on scanning microscopy have been performed. A Fresnel zone plate fabricated by the electron-beam lithography technique is used as an X-ray focusing device. The material of the zone structure is tantalum with thickness of about 1 µm, and the outermost zone width of the zone plate is 0.25 µm. A Focused Spot Size measured by knife-edge scanning is 0.3 µm at an X-ray energy of 8 keV. Closer evaluation of the spatial resolution has been done by observing resolution test patterns in a scanning X-ray microscopy experiment, and fine patterns with a 0.2 µm-structure have been resolved.
