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.
