  • Patent number: 10921537
    Abstract: An optical communication subassembly includes one or more optoelectronic devices, one or more optical elements, and a transceiver light coupling unit. Each optical element is configured to change a divergence of the outgoing light relative to a divergence of the incoming light and is spaced apart from and optically aligned with a corresponding optoelectronic device. The transceiver light coupling unit has a mating surface configured for mating with a connector light coupling unit attached to an optical waveguide. A mating direction of the optical light coupling unit forms an angle with the mating surface of the transceiver light coupling unit such that when the connector light coupling unit mates with the transceiver light coupling unit, the angle between the mating direction of the connector light coupling unit and the mating surface of the transceiver light coupling unit causes the optical waveguide to bend.

    Abstract: A method of fabricating a waveguide mode expander includes providing a substrate including a waveguide, bonding a chiplet including multiple optical material layers in a mounting region adjacent an output end of the waveguide, and selectively removing portions of the chiplet to form tapered stages that successively increase in number and lateral size from a proximal end to a distal end of the chiplet. The first optical material layer supports an input mode substantially the same size as a mode exiting the waveguide. One or more of the overlying layers, when combined with the first layer, support a larger, output optical mode size. Each tapered stage of the mode expander is formed of a portion of a respective layer of the chiplet. The first layer and the tapered stages form a waveguide mode expander that expands an optical mode of light traversing the chiplet.

  • Patent number: 10852530
    Abstract: Optical spectroscopy is a widely used method to identify the chemical composition of materials and the characteristics of optical signals. Silicon based integrated photonics offers a platform for many optical functions through microelectromechanical systems (MEMS) and microoptoelectromechanical systems (MOEMS), silicon waveguides, integrated CMOS electronics and hybrid integration of compound semiconductor elements for optical gain. Accordingly, it would be beneficial to provide advanced optical tools for techniques such as optical spectroscopy and optical tomography exploiting MOEMS to provide swept filters that offer improved performance, increased integration, reduced footprint, reduced power consumption, increased flexibility, reconfigurability, and lower cost. Further, such MOEMS elements can support the provisioning of swept optical sources, swept filters, swept receivers etc. in the planar waveguide domain without free space optics.
