Abstract: Embodiments described herein may be related to apparatuses, processes, and techniques related to a bidirectional optical grating coupler that may be used for testing. A photonic apparatus includes a first layer with electro-optical circuitry that is optically coupled with a bidirectional optical grating coupler. A second layer is physically coupled with a first side of the first layer and includes a first light path to optically coupled with the bidirectional optical grating coupler. A third layer is physically coupled with a second side of the first layer opposite the first side of the first layer, and includes a second light path that optically couples with the bidirectional grating coupler. Operational testing of the electro-optical circuitry is based in part on light received or transmitted through the second light path. Other embodiments may be described and/or claimed.

Abstract: Technologies for optical coupling to photonic integrated circuit (PIC) dies are disclosed. In one illustrative embodiment, a PIC die has one or more waveguides. A lens array is positioned adjacent the PIC die. Light from waveguides of the PIC die reflects off of a reflective surface of the lens array. The reflective surface directs the light from the PIC die towards lenses in the lens array. The lenses collimate the light, facilitating coupling of light to and from other components. The reflective surface on the lens array may be oriented at any suitable angle, resulting in a collimated beam of light that is oriented at any suitable angle.

Abstract: A semiconductor package comprises an interposer and a photonics die. The photonics die has a front side with an on-chip fiber connector and solder bumps, the photonics die over the interposer with the on-chip fiber connector and the solder bumps facing away from the interposer. A patch substrate is mounted on the interposer adjacent to the photonics die. A logic die is mounted on the patch substrate with an overhang past an edge of the patch substrate and the overhang is attached to the solder bumps of the photonics die. An integrated heat spreader (IHS) is over the logic die such that the photonics die does not directly contact the IHS.
