    摘要： An optical switching element for use in an optical cross-bar array, includes a magnetically responsive curtain that switches between an extended state and a deflected state in response to an applied switching-field. The switching element includes a curtain that moves in response to a magnetic field. The curtain has a fixed edge attached to a substrate and a free edge opposite the fixed edge. A first magnetic-field source magnetically coupled to the curtain generates a first magnetic field that urges the curtain into an extended position in which the curtain intercepts the optical beam. A second magnetic-field source, also magnetically coupled to the curtain, generates a second magnetic field that urges the curtain into a deflected position in which the curtain avoids intercepting the optical beam.

    摘要： An optical recording head is provided which includes a slider body having a leading edge. A void is formed in the slider body to receive a sphere of optically transparent material. The sphere is inserted into the void such that a portion of the sphere protrudes from the slider body. The protruding portion is lapped to be coplanar with a surface of the slider body to form a near-field lens. A mesa may be formed onto the lapped portion and may include a coil. The slider body, mesa, near-field lens, and coil may be formed in one batch process.

    摘要： Optical heads having a monolithic layer for interfacing storage media and methods for manufacturing such heads. In one embodiment, the substrate has first and second surfaces to define a through hole which forms an optical path and a lens with a spherical surface and a flat surface opposing the spherical surface is disposed in the optical path in the through hole. The flat surface is coplanar with a flat portion of the second surface. The optical head also includes a transparent layer contiguously formed over both the flat surface of the lens and the second surface of the substrate to form a monolithic layer. The refractive index of the additional layer may match that of the lens. In addition, the additional layer may have a material hardness greater than that of the lens to protect the lens and to reduce wear.
