  • Patent number: 10048450
    Abstract: Embodiments herein include an optical system, an optical component, and an associated method of passive alignment in which complementary magnetic patterns are used to provide passive alignment between optical elements. The magnetic coupling between the magnetic patterns operates to align optical elements in at least two dimensions. The magnetic coupling provides a temporary holding force on the optical elements until the optical elements are secured using epoxy or other adhesive.

  • Patent number: 9575267
    Abstract: Embodiments herein include an optical system that passively aligns an optical component (e.g., a fiber array connector, lens array, lens body, etc.) with a semiconductor substrate using trenches that mate with optical fiber stubs. In one embodiment, the trenches are etched into the semiconductor substrate which provides support to optical devices (e.g., lasers, lens arrays, photodetectors, etc.) that transmit optical signals to, or receive optical signals from, the optical component. An underside of the optical component is etched to include at least two grooves (e.g., V-grooves) for receiving optical fiber stubs. In one embodiment, the optical fiber stubs are a portion of optical fiber that includes the core and cladding but not the insulative jacket. Once the fiber stubs are attached to the grooves, the fiber stubs are disposed into the trenches in the semiconductor substrate thereby passively aligning the optical component to the optical device on the substrate.
