Top-side optical couplers for advanced package architectures

Abstract

A device may include an electronic-photonic assembly comprising: a photonic integrated circuit (PIC) comprising a waveguide defining a waveguide plane, an electronic integrated circuit (EIC) attached to the PIC; and an encapsulant at least partially encapsulating the EIC. A device may include an optical coupler attached to the PIC, wherein the optical coupler is configured to collimate, in a first direction that is angled relative to the waveguide plane, light emitted by the PIC upon being guided by the waveguide. A device may include an optical assembly comprising a detachable plug and a fiber attached to the detachable plug, wherein the optical assembly is positioned to receive the collimated light from the optical coupler.
