Abstract: Solder reflow compatible connections between optical components are provided by use of reflow compatible epoxies to bond optical components and remain bonded between the optical components at temperatures of at least 260 degrees Celsius for at least five minutes. In some embodiments, the reflow compatible epoxy is index matched to the optical channels in the optical components and is disposed in the light path therebetween. In some embodiments, a light path is defined between the optical channels through at least a portion of an air gap between the optical components.

Abstract: Periscope assemblies are provided which have a light path that travels in a first plane along the first waveguide, a second plane along the second waveguide that is parallel to the first plane, and along a third plane along the third waveguide that intersects the first plane and the second plane. In some examples the periscope assembly includes first and second carriers comprising respective first and second waveguides and defining respective first and second cavities in which a third carrier comprising a third waveguide is disposed and optionally includes an optical component. In some examples, the cavities are defined in one or more carriers on a mating surface, on a side opposite to the mating surface, or on a side perpendicular to a mating surface.

Abstract: Embodiments herein describe an optical array unit configured to couple a photonic die with a plurality of optical fibers. The optical array unit includes alignment features which engage with alignment features on a corresponding photonic die. The engaged alignment features reduce the need for active alignment while also reducing the complexities of traditional passive alignment features.

Abstract: An opto-electronic package is described. The opto-electronic package is manufactured using a fan out wafer level packaging to produce dies/frames which include connection features. Additional structures such as heat exchanged structures are joined to a connection component and affixed to packages, using the connection features, to provide structural support and heat exchange to heat generating components in the package, among other functions.
