Abstract
An apparatus comprising a plurality of alignment couplers, wherein the alignment couplers are equally spaced a first length apart from each other along a first surface, a plurality of photodetectors optically coupled to the plurality of alignment couplers, a memory, and a processor coupled to the photodetectors and the memory, wherein the memory comprises computer executable instructions stored in a non-transitory computer readable medium that when executed by the processor cause the processor to receive an electrical signal in response to at least one of the photodetectors detecting a first light, and determine an edge coupling alignment based on the electrical signal, wherein the edge coupling alignment is aligned when the electrical signal indicates two photodetectors of the plurality of photodetectors detect the first light, and wherein the edge coupling alignment is misaligned when the electrical signal indicates only one photodetector of the plurality of photodetectors detects the first light.
