Abstract: A ferrule mold having a reverse-image of a through-hole array for optical fibers is formed. A non-polymeric ferrule material is deposited in the reverse-image mold, followed by removing the mold to create a multi-fiber connector ferrule having at least two fiber through-holes. An optical fiber is inserted in each through-hole until each fiber endface is positioned approximately even with a connection surface of the ferrule. A fiber recess for each of the optical fibers is formed such that each fiber is recessed from the multi-fiber ferrule connection surface by a distance of at least 0.1 micron. The recess may be formed by differential polishing of the non-polymeric ferrule and endfaces of the optical fibers. Alternatively, a layer of spacer material may be deposited over the multi-fiber ferrule connection surface. An antireflection coating is deposited over the ferrule connection surface and ends of the recessed fibers.

Abstract: A headlamp unit based on a PBS includes a lens and a beam splitter. Viewed from a reverse light path, parallel light is refracted twice by an incident surface and an emergent surface of the lens and then converged in at least two focuses through the beam splitter. Each focus corresponds to a light path system, and the light path systems may be turned on simultaneously or separately to obtain a corresponding headlamp light pattern. Through beam combination of the PBS, two optical systems may achieve different illumination light shapes through on-off combination of light sources, and the two optical systems do not interfere with each other. The PBS obtains at least two accurate focus positions for the focuses of the lens, and an ideal light pattern may be accurately obtained. An upper beam light pattern may partially cover a lower beam light pattern.
