    Abstract: Embodiments disclosed herein include multi-die packages with open cavity bridges. In an example, an electronic apparatus includes a package substrate having alternating metallization layers and dielectric layers. The package substrate includes a first plurality of substrate pads and a second plurality of substrate pads. The package substrate also includes an open cavity between the first plurality of substrate pads and the second plurality of substrate pads, the open cavity having a bottom and sides. The electronic apparatus also includes a bridge die in the open cavity, the bridge die including a first plurality of bridge pads, a second plurality of bridge pads, and conductive traces. An adhesive layer couples the bridge die to the bottom of the open cavity. A gap is laterally between the bridge die and the sides of the open cavity, the gap surrounding the bridge die.

    Abstract: An electronic device may include a photonic integrated circuit (PIC) coupled with a substrate. The PIC may communicate a photonic signal with one or more optical fibers. The PIC may process the photonic signal into an electronic signal. The electronic device may include an electronic integrated circuit (EIC) coupled with the substrate. The EIC may communicate with the PIC. The EIC may transmit the electronic signal to the PIC. The EIC may receive the electronic signal from the PIC. The electronic device may include a lens assembly. The lens assembly may include at least one gradient refractive index (GRIN) lens.
