  • Multifaceted prism to cause the overlap of beams from a stack of diode laser bars
    Patent number: 7639722
    Abstract: An optical element for homogenizing and, possibly, concentrating the output from high-power two-dimensional semiconductor laser arrays, which has the basic shape of a convex-flat cylindrical lens with a facet cut into the convex surface for each individual semiconductor laser bar.
    Type: Grant

  • High-density optical interconnect with an increased tolerance of misalignment
    Patent number: 6452705
    Abstract: A free-space optical interconnect architecture is presented that is tolerant of the lateral misalignment of integrated circuit boards in multi-chip module packages. Each transmitter has a different wavelength and correspondingly sensitive detector. The transmitted beams are spread such that the beams' half angles are slightly greater than the maximum expected misalignment.

  • Spatially coherent diode laser with lenslike media and feedback from straight-toothed gratings
    Patent number: 5727016
    Abstract: In a surface emitting semiconductor laser, a variable index of refraction layer having an approximately parabolically shaped trough therein is positioned adjacent the active lasing region and a straight toothed second order diffraction grating coacts with the refraction layer to produce a broad spatially coherent output beam.

  • Unstable optical resonator with self-imaging aperture
    Patent number: 4267524
    Abstract: An unstable optical resonator with self-imaging aperture having at least two reflecting surfaces and a primary outcoupling aperture in optical alignment with each other. In the resonator the result of a single round-trip propagation is to image the primary aperture at its own plane. The self-imaging condition is met when a pass through the resonator, starting at the outcoupling aperture, produces an infinite Fresnel number.
