Aspects described herein include an apparatus supporting optical alignment with one or more optical waveguides optically exposed along an edge of a photonic integrated circuit (IC). The apparatus comprises a frame body comprising an upper portion defining a reference surface, and a lateral portion defining an interface for an optical connector connected with one or more optical fibers. The lateral portion comprises one or more optical components defining an optical path through the lateral portion. The one or more optical components are arranged relative to the reference surface such that the one or more optical components align with (i) the one or more optical waveguides along at least one dimension when the reference surface contacts a top surface of an anchor IC, and with (ii) the one or more optical fibers when the optical connector is connected at the interface.

Connecting optical connector with co-packaged optical device

A method of manufacturing an optical apparatus comprises forming an unfinished endface of a fiber array unit (FAU) that provides an arrangement of one or more optical fibers. The one or more optical fibers terminate at the unfinished endface. The method further comprises optically aligning the FAU with an external light-carrying medium. The one or more optical fibers are optically coupled with the external light-carrying medium through the unfinished endface.

Fiber array unit with unfinished endface

An apparatus comprises a plurality of optical fibers and a lid member having one or more surfaces with grooves formed therein. The lid member defines a first plurality of grooves that are each dimensioned to partly receive an optical fiber of the plurality of optical fibers. The apparatus further comprises a substrate comprising a plurality of waveguides arranged at a predefined depth relative to a reference surface of the substrate, and a plurality of ribs extending from the reference surface. Each rib of the plurality of ribs is dimensioned to engage with a respective groove of a second plurality of grooves of the lid member. Engaging the plurality of ribs of the substrate with the second plurality of grooves of the lid member provides an optical alignment of the plurality of optical fibers with the plurality of waveguides.
