  • Patent number: 10886420
    Abstract: The wafer-level manufacturing method makes possible to manufacture ultrathin optical devices such as opto-electronic modules. A clear encapsulation is applied to an initial wafer including active optical components and a wafer-size substrate. Thereon, a photostructurable spectral filter layer is produced which defines apertures. Then, trenches are produced which extend through the clear encapsulation and establish sidewalls of intermediate products. Then, an opaque encapsulation is applied to the intermediate products, thus filling the trenches and producing aperture stops. Cutting through the opaque encapsulation material present in the trenches, singulated optical modules are produced, wherein side walls of the intermediate products are covered by the opaque encapsulation material. The wafer-size substrate can be attached to a rigid carrier wafer during most process steps.

  • Patent number: 9846280
    Abstract: A two-dimensional (2D) optical fiber array component takes the form of a (relatively inexpensive) fiber guide block that is mated with a precision output element. The guide block and output element are both formed to include a 2D array of through-holes that exhibit a predetermined pitch. The holes formed in the guide block are relatively larger than those in precision output element. A loading tool is used to hold a 1×N array of fibers in a fixed position that exhibits the desired pitch. The loaded tool (holding the pre-aligned 1×N array of fibers) is then inserted through the aligned combination of the guide block and output element, and the fiber array is bonded to the guide block. The tool is then removed, re-loaded, and the process continued until all of the 1×N fiber arrays are in place. By virtue of using a precision tool to load the fibers, the guide block does not have to be formed to exhibit precise through-hole dimensions, allowing for a relatively inexpensive guide block to be used.

  • 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.

  • Patent number: 9383539
    Abstract: Multi-fiber, fiber optic cable assemblies may be configured so that the terminal ends of the cables have pre-assembled back-post assemblies that include pre-assembled ferrules, such as MPO ferrules that meet the requisite tolerances needed for fiber optic transmissions. To protect the pre-assembled components from damage prior to and during installation, pre-assembled components may be enclosed within a protective housing. The housing with pre-assembled components may be of a size smaller than fully assembled connectors so as to be sized to fit through a conduit. The remaining connector housing components for the multi-fiber connectors may be provided separately and may be configured to be attached to the back-post assembly after installation of the cable.

  • Patent number: 9274281
    Abstract: In an optical-fiber-spliced portion reinforcing heating device of the invention, a pressing force that is applied to a sleeve by a second force-applying member is greater than a tension that is applied to an optical fiber by a first force-applying member; in a state in which a tension is applied to the optical fiber by the first force-applying member, a backward movable range of one clamp that applies a tension is ensured in the longitudinal direction of the optical fiber and in a direction away from heater; and as a result of ensuring a forward movable range in which it can move toward the heater, one clamp moves in a direction in which a tension that is applied to the optical fiber as a result of pressing the sleeve by the heaters and by the second force-applying member is diminished.
