    Abstract: Embodiments of the invention include an optoelectronic package that allows for in situ alignment of optical fibers. In an embodiment, the optoelectronic package may include an organic substrate. Embodiments include a cavity formed into the organic substrate. Additionally, the optoelectronic package may include an actuator formed on the organic substrate that extends over the cavity. In one embodiment, the actuator may include a first electrode, a piezoelectric layer formed on the first electrode, and a second electrode formed on the piezoelectric layer. According to an additional embodiment of the invention, the actuator may include a first portion and a second portion. In order to allow for resistive heating and actuation driven by thermal expansion, a cross-sectional area of the first portion of the beam may be greater than a cross-sectional area of the second portion of the beam.

    Abstract: Apparatuses, systems and methods associated with hermetic encapsulation for package assemblies are disclosed herein. In embodiments, a package assembly may include a package substrate that includes a guard ring, wherein the guard ring extends from a surface of the package substrate and around a circumference of a cavity. The package assembly may further include a component coupled to the guard ring by a solder joint along an entirety of the guard ring, wherein the cavity is located between the package substrate and the component and the cavity is hermetically-sealed via the guard ring and the solder joint. Other embodiments may be described and/or claimed.
