  • Plastic composite lens array in optical networks
    Patent number: 10996409
    Abstract: An optoelectronic assembly may include a PCB and an optical lens. The PCB includes a top surface where at least a portion of the top surface includes a first material with a first thermal property. The optical lens includes a lens frame and an optical portion positioned within the lens frame. The lens frame is coupled to the top surface of the PCB. The lens frame includes a second material with a second thermal property, the second material being different from the first material. The optical portion positioned includes a third material with a third thermal property, the third material being different from the first material and the second material. The third material is optically transparent.

  • Flex-less multilayer ceramic substrate
    Patent number: 9900974
    Abstract: In one example embodiment, an optoelectronic assembly includes a multilayer ceramic substrate that includes multiple ceramic layers and a via disposed through at least one of the ceramic layers. The via may be formed from a conductive material that is configured to communicate a signal through the via. The multilayer ceramic substrate may be configured to dissipate heat emitted by an electronic component coupled to the multilayer ceramic substrate.

  • Thermally tuned filter having a pre-stressed membrane
    Patent number: 7061659
    Abstract: A thermally tuned filter having a pre-stressed membrane. The thermally tuned filter includes a handle layer, a dielectric layer positioned proximate to the handle layer, and a device layer positioned proximate to the handle layer. The device layer includes an optical device. A pre-stressed membrane is positioned proximate to the device layer; a tensile prestress of the pre-stressed membrane increases the natural frequency of the thermally tuned filter.
