Abstract
Described herein are photonic devices and methods of manufacturing the same. The photonic devices include a photonic integrated circuit (PIC) disposed on a substrate and a socket configured to receive a pluggable optical coupler to couple the PIC to one or more optical fibers. Manufacturing the photonic devices may include removing a portion of the PIC to expose through-silicon-vias (TSVs) of the PIC, coupling electronic integrated circuits (EIC) to the PIC, and forming a mold around portions of the EICs. The architecture of the photonic devices enables pluggable fiber array units in multi-die configurations while maintaining low optical loss through wafer-level assembly.

A photonic device, comprising:
- a substrate;
- an electro-optical assembly comprising:
- a photonic integrated circuit (PIC) disposed on the substrate, the PIC having a first surface facing the substrate and a second surface opposite the first surface;
- an electronic integrated circuit (EIC) coupled to the PIC at the second surface;
- an optical assembly having an optical fiber;
- and
- an optical coupler disposed on the first surface of the PIC configured to optically couple the electro-optical assembly with the optical fiber when the optical assembly is coupled with the electro-optical assembly.
A method for manufacturing a photonic device, the method comprising:
- receiving a photonic integrated circuit (PIC), the PIC having a first surface and a second surface opposite the first surface;
- forming an electro-optical assembly by coupling an electronic integrated circuit (EIC) to the PIC at the second surface;
- securing an optical coupler to the first surface;
- securing the electro-optical assembly to a substrate at the first surface;
- and
- coupling an optical assembly to the electro-optical assembly, the optical assembly having an optical fiber, wherein the optical coupler is configured to optically couple the optical fiber to the electro-optical assembly when the optical assembly is coupled with the electro-optical assembly.
