Abstract:
A photonic integrated circuit (PIC) fan-out package and related methods of forming same are disclosed. The PIC fan-out package includes: an overmold body; a PIC die in the overmold body, the PIC die including electro-optic circuitry; a plurality of optical fiber stubs operatively coupled to the electro-optic circuitry; an edge fiber coupling interface in a lateral side of the overmold body for coupling the plurality of optical fiber stubs to external optical fibers using a connector; an ancillary device in the overmold body; a redistribution wiring layer (RDL) interposer adjacent the overmold body and electrically connected to the PIC die and the ancillary device; and a ball grid array (BGA) electrically coupled to the PIC die and the ancillary device by the RDL interposer, the BGA configured to electrically couple the PIC die and the ancillary device to a printed circuit board (PCB).

Claim (Index 17):
A method, comprising:\n mounting a plurality of photonic integrated circuit (PIC) dies to a first carrier, each PIC die including a plurality of V-groove receptacles on an opposing vertically facing side of the respective PIC die from the first carrier, at least two of the plurality of V-groove receptacles each configured to receive and operatively couple an optical fiber stub to the respective PIC die; individually mounting an optical fiber stub into each of the at least two of the plurality of V-groove receptacles; separating each PIC die from the first carrier; mounting a plurality of sets of a selected PIC die and an ancillary device to a second carrier, wherein the plurality of V-groove receptacles and the optical fiber stubs are adhered to the second carrier; overmolding of the plurality of sets on the second carrier; removing the second carrier, creating a set of connected modules, each module including a selected PIC die and a respective ancillary device; forming a redistribution layer (RDL) interposer for each of the plurality of connected modules, each RDL interposer electrically connected to the selected PIC die and the respective ancillary device of a respective connected module; dicing a selected module from the set of connected modules; forming an edge fiber coupling interface by exposing a portion of each optical fiber stub on the lateral side of the overmold body of the selected module, creating fiber optic couplings for optical coupling to external optical fibers; and forming a ball grid array (B GA) on the RDL interposer of the selected module, the BGA being electrically connected to the selected PIC die and the respective ancillary device by the RDL interposer, the BGA configured to electrically couple the selected PIC die and the respective ancillary device to a printed circuit board (PCB).
