  • Phase offset integrated solid immersion mirror and lens for a general phase front
    Patent number: 8085473
    Abstract: An apparatus includes a core waveguide for directing electromagnetic radiation to a focal point, the core waveguide having a first interface on a first side of a longitudinal axis for directing a first plurality of rays of the electromagnetic radiation to a focal point and a second interface on a second side of the longitudinal axis for directing a second plurality of rays of the electromagnetic radiation to the focal point, wherein the first and second interfaces are shaped such that at the focal point, the second plurality of rays are about 180° out of phase with respect to the first plurality of rays.
    Type: Grant

  • Solid immersion mirror
    Patent number: 6980374
    Abstract: An apparatus for focusing electromagnetic radiation comprises a planar solid immersion mirror including edges for reflecting an electromagnetic wave toward a focal point adjacent to a truncated end of the planar solid immersion mirror, and an interface for diverting a portion of the electromagnetic wave from a central portion of the planar solid immersion mirror to the edges for subsequent reflection toward the focal point.
