1. An optical fiber photonic integrated chip (PIC) connector interface comprising:
at least one low-profile optical fiber comprising an end face at a first end, at least one core and a cladding layer, wherein the end face is non-rotationally symmetric with respect to the core, and the cladding layer comprises at least one minimum perimeter point that is a minimum distance from the at least one core as compared to remaining perimeter points of the cladding, and the at least one low-profile optical fiber comprises a second end configured for optical coupling to an optical connector, wherein the optical fiber PIC connector interface further comprises a ferrule comprising at least one bore, and the second end of the at least one low-profile optical fiber is disposed within the at least one bore such that an adhesive is provided within a void between the one or more surfaces of the cladding defining the at least one minimum perimeter point of the at least one low-profile optical fiber and an interior surface of the at least one bore; and
an interconnect substrate comprising a fiber mounting surface, and a mechanical coupling surface, wherein the at least one low-profile optical fiber is disposed on the fiber mounting surface such that one or more surfaces of the cladding defining the at least one minimum perimeter point faces away from the fiber mounting surface.
