Abstract
Embodiments of alignment structures are disclosed that enable the alignment of a fiber attach unit (FAU) and the optical fibers contained therein to optical components on optical interposers or substrates on which photonic integrated circuits (PICs) are formed. Alignment of the optical fibers is enabled without the requirement for powering of the active optoelectrical devices in the PIC, but rather use an external testing apparatus to provide one or more optical signals to facilitate alignment. Methods for alignment using embodiments of the alignment structure is also disclosed.

A method for optically aligning an optical fiber coupled to a mounting component to an optical or optoelectrical element on a substrate, the method comprising
- forming a first optical component on the substrate at a first distance to the optical or optoelectrical element,
- wherein the first distance is related to a second distance between the optical fiber and a second optical component on the mounting component,
- wherein the first and second distances are related in such a way to enable an optical alignment of the optical fiber to the optical or optoelectrical element by optically aligning the first optical component to the second optical component.
A method for optically aligning an optical fiber coupled to a mounting component to an optical or optoelectrical element on a substrate, the method comprising
- forming a first optical component on the substrate at a first distance to the optical or optoelectrical element,
- forming a second optical component on the mounting component at a second distance to the optical fiber,
- wherein the second distance is related to the first distance in such a way to enable an optical alignment of the optical fiber to the optical or optoelectrical element by optically aligning the first optical component to the second optical component,
- coupling the mounting component to the substrate,
- optically aligning the first optical component to the second optical component using an optical signal transmitting between the first and second optical components.
A substrate comprising
- an optical or optoelectrical element,
- a first optical component at a first distance to the optical or optoelectrical element,
- wherein the first optical component is configured to send or to receive an optical signal between in a first direction not parallel to a lateral surface of the substrate,
- a recess configured to accept a mounting component,
- wherein the mounting component comprises a second optical component and an optical fiber,
- wherein the second optical component is disposed at a second distance to the optical fiber,
- wherein the second distance is related to the first distance in such a way to enable an optical alignment of the optical fiber to the optical or optoelectrical element by optically aligning the first optical component to the second optical component when the mounting component is coupled to the substrate at the recess.
