Claim 0:
1. A fiber optic assembly comprising:
a support substrate having a first surface comprising a plurality of V-grooves;
a signal-fiber array supported on the first surface of the support substrate, the signal-fiber array comprising a plurality of optical fibers disposed in the plurality of V-grooves, wherein each of the plurality of optical fibers comprises a first exposed datum surface at a top of the optical fibers opposite the support substrate and wherein some of the plurality of optical fibers are defined as edge optical fibers and comprise a second exposed datum surface; and
an adhesive, disposed on the plurality of optical fibers and the support substrate, that bonds the plurality of optical fibers to each other and to the support substrate,
wherein the adhesive resides below a plane defined by the first datum surface to not interfere with mating of the first exposed datum surface or the second datum surface, and wherein the second exposed datum surface enables lateral alignment of the fiber optic assembly with a waveguide substrate, and wherein each optical fiber is spaced apart from adjacent optical fibers of the plurality of optical fibers at a precise pitch, and each optical fiber is directly adjacent an adjacent optical fiber.
