Abstract: Embodiments disclosed herein include electronic packages and methods of forming electronic packages. In an embodiment, the electronic package comprises a package substrate, a die coupled to the package substrate, a photonics integrated circuit (PIC) coupled to the die, and a fiber array unit (FAU) optically coupled to the PIC. In an embodiment, the FAU has a base with a first width and a protrusion with a second width that is smaller than the first width.

Abstract: An electronic device and associated methods are disclosed. In one example, the electronic device includes a laser package. In selected examples, the laser package can include a substrate having a substrate front surface and defining a cavity that extends into the substrate front surface. The laser package can further include a photonic integrated circuit (PIC) attached to the substrate within the cavity at a first surface of the PIC, and laser circuitry communicably coupled to a second surface of the PIC opposite the first surface.
